    <![CDATA[Provides access to configuration parameters.

 <h4 id="Resources">Resources</h4>

 <p>Configurations are specified by resources. A resource contains a set of
 name/value pairs as XML data. Each resource is named by either a 
 <code>String</code> or by a {@link Path}. If named by a <code>String</code>, 
 then the classpath is examined for a file with that name.  If named by a 
 <code>Path</code>, then the local filesystem is examined directly, without 
 referring to the classpath.

 <p>Unless explicitly turned off, Hadoop by default specifies two 
 resources, loaded in-order from the classpath: <ol>
 <li><tt>
 <a href="{@docRoot}/../hadoop-project-dist/hadoop-common/core-default.xml">
 core-default.xml</a></tt>: Read-only defaults for hadoop.</li>
 <li><tt>core-site.xml</tt>: Site-specific configuration for a given hadoop
 installation.</li>
 </ol>
 Applications may add additional resources, which are loaded
 subsequent to these resources in the order they are added.
 
 <h4 id="FinalParams">Final Parameters</h4>

 <p>Configuration parameters may be declared <i>final</i>. 
 Once a resource declares a value final, no subsequently-loaded 
 resource can alter that value.  
 For example, one might define a final parameter with:
 <tt><pre>
  &lt;property&gt;
    &lt;name&gt;dfs.hosts.include&lt;/name&gt;
    &lt;value&gt;/etc/hadoop/conf/hosts.include&lt;/value&gt;
    <b>&lt;final&gt;true&lt;/final&gt;</b>
  &lt;/property&gt;</pre></tt>

 Administrators typically define parameters as final in 
 <tt>core-site.xml</tt> for values that user applications may not alter.

 <h4 id="VariableExpansion">Variable Expansion</h4>

 <p>Value strings are first processed for <i>variable expansion</i>. The
 available properties are:<ol>
 <li>Other properties defined in this Configuration; and, if a name is
 undefined here,</li>
 <li>Properties in {@link System#getProperties()}.</li>
 </ol>

 <p>For example, if a configuration resource contains the following property
 definitions: 
 <tt><pre>
  &lt;property&gt;
    &lt;name&gt;basedir&lt;/name&gt;
    &lt;value&gt;/user/${<i>user.name</i>}&lt;/value&gt;
  &lt;/property&gt;
  
  &lt;property&gt;
    &lt;name&gt;tempdir&lt;/name&gt;
    &lt;value&gt;${<i>basedir</i>}/tmp&lt;/value&gt;
  &lt;/property&gt;</pre></tt>

 When <tt>conf.get("tempdir")</tt> is called, then <tt>${<i>basedir</i>}</tt>
 will be resolved to another property in this Configuration, while
 <tt>${<i>user.name</i>}</tt> would then ordinarily be resolved to the value
 of the System property with that name.
 <p>When <tt>conf.get("otherdir")</tt> is called, then <tt>${<i>env.BASE_DIR</i>}</tt>
 will be resolved to the value of the <tt>${<i>BASE_DIR</i>}</tt> environment variable.
 It supports <tt>${<i>env.NAME:-default</i>}</tt> and <tt>${<i>env.NAME-default</i>}</tt> notations.

      <![CDATA[Creates a symbolic link to an existing file. An exception is thrown if 
 the symlink exits, the user does not have permission to create symlink,
 or the underlying file system does not support symlinks.
 
 Symlink permissions are ignored, access to a symlink is determined by
 the permissions of the symlink target.
 
 Symlinks in paths leading up to the final path component are resolved 
 transparently. If the final path component refers to a symlink some 
 functions operate on the symlink itself, these are:
 - delete(f) and deleteOnExit(f) - Deletes the symlink.
 - rename(src, dst) - If src refers to a symlink, the symlink is 
   renamed. If dst refers to a symlink, the symlink is over-written.
 - getLinkTarget(f) - Returns the target of the symlink. 
 - getFileLinkStatus(f) - Returns a FileStatus object describing
   the symlink.
 Some functions, create() and mkdir(), expect the final path component
 does not exist. If they are given a path that refers to a symlink that 
 does exist they behave as if the path referred to an existing file or 
 directory. All other functions fully resolve, ie follow, the symlink. 
 These are: open, setReplication, setOwner, setTimes, setWorkingDirectory,
 setPermission, getFileChecksum, setVerifyChecksum, getFileBlockLocations,
 getFsStatus, getFileStatus, exists, and listStatus.
 
 Symlink targets are stored as given to createSymlink, assuming the 
 underlying file system is capable of storing a fully qualified URI.
 Dangling symlinks are permitted. FileContext supports four types of 
 symlink targets, and resolves them as follows
 <pre>
 Given a path referring to a symlink of form:
 
   <---X---> 
   fs://host/A/B/link 
   <-----Y----->
 
 In this path X is the scheme and authority that identify the file system,
 and Y is the path leading up to the final path component "link". If Y is
 a symlink  itself then let Y' be the target of Y and X' be the scheme and
 authority of Y'. Symlink targets may:
 
 1. Fully qualified URIs
 
 fs://hostX/A/B/file  Resolved according to the target file system.
 
 2. Partially qualified URIs (eg scheme but no host)
 
 fs:///A/B/file  Resolved according to the target file system. Eg resolving
                 a symlink to hdfs:///A results in an exception because
                 HDFS URIs must be fully qualified, while a symlink to 
                 file:///A will not since Hadoop's local file systems 
                 require partially qualified URIs.
 
 3. Relative paths
 
 path  Resolves to [Y'][path]. Eg if Y resolves to hdfs://host/A and path 
       is "../B/file" then [Y'][path] is hdfs://host/B/file
 
 4. Absolute paths
 
 path  Resolves to [X'][path]. Eg if Y resolves hdfs://host/A/B and path
       is "/file" then [X][path] is hdfs://host/file
 </pre>

    <![CDATA[The FileContext class provides an interface to the application writer for
 using the Hadoop file system.
 It provides a set of methods for the usual operation: create, open, 
 list, etc 
 
 <p>
 <b> *** Path Names *** </b>
 <p>
 
 The Hadoop file system supports a URI name space and URI names.
 It offers a forest of file systems that can be referenced using fully
 qualified URIs.
 Two common Hadoop file systems implementations are
 <ul>
 <li> the local file system: file:///path
 <li> the hdfs file system hdfs://nnAddress:nnPort/path
 </ul>
 
 While URI names are very flexible, it requires knowing the name or address
 of the server. For convenience one often wants to access the default system
 in one's environment without knowing its name/address. This has an
 additional benefit that it allows one to change one's default fs
  (e.g. admin moves application from cluster1 to cluster2).
 <p>
 
 To facilitate this, Hadoop supports a notion of a default file system.
 The user can set his default file system, although this is
 typically set up for you in your environment via your default config.
 A default file system implies a default scheme and authority; slash-relative
 names (such as /for/bar) are resolved relative to that default FS.
 Similarly a user can also have working-directory-relative names (i.e. names
 not starting with a slash). While the working directory is generally in the
 same default FS, the wd can be in a different FS.
 <p>
  Hence Hadoop path names can be one of:
  <ul>
  <li> fully qualified URI: scheme://authority/path
  <li> slash relative names: /path relative to the default file system
  <li> wd-relative names: path  relative to the working dir
  </ul>   
  Relative paths with scheme (scheme:foo/bar) are illegal.
  
  <p>
  <b>****The Role of the FileContext and configuration defaults****</b>
  <p>
  The FileContext provides file namespace context for resolving file names;
  it also contains the umask for permissions, In that sense it is like the
  per-process file-related state in Unix system.
  These two properties
  <ul> 
  <li> default file system i.e your slash)
  <li> umask
  </ul>
  in general, are obtained from the default configuration file
  in your environment,  (@see {@link Configuration}).
  
  No other configuration parameters are obtained from the default config as 
  far as the file context layer is concerned. All file system instances
  (i.e. deployments of file systems) have default properties; we call these
  server side (SS) defaults. Operation like create allow one to select many 
  properties: either pass them in as explicit parameters or use
  the SS properties.
  <p>
  The file system related SS defaults are
  <ul>
  <li> the home directory (default is "/user/userName")
  <li> the initial wd (only for local fs)
  <li> replication factor
  <li> block size
  <li> buffer size
  <li> encryptDataTransfer 
  <li> checksum option. (checksumType and  bytesPerChecksum)
  </ul>

 <p>
 <b> *** Usage Model for the FileContext class *** </b>
 <p>
 Example 1: use the default config read from the $HADOOP_CONFIG/core.xml.
   Unspecified values come from core-defaults.xml in the release jar.
  <ul>  
  <li> myFContext = FileContext.getFileContext(); // uses the default config
                                                // which has your default FS 
  <li>  myFContext.create(path, ...);
  <li>  myFContext.setWorkingDir(path)
  <li>  myFContext.open (path, ...);  
  </ul>  
 Example 2: Get a FileContext with a specific URI as the default FS
  <ul>  
  <li> myFContext = FileContext.getFileContext(URI)
  <li> myFContext.create(path, ...);
   ...
 </ul> 
 Example 3: FileContext with local file system as the default
  <ul> 
  <li> myFContext = FileContext.getLocalFSFileContext()
  <li> myFContext.create(path, ...);
  <li> ...
  </ul> 
 Example 4: Use a specific config, ignoring $HADOOP_CONFIG
  Generally you should not need use a config unless you are doing
   <ul> 
   <li> configX = someConfigSomeOnePassedToYou.
   <li> myFContext = getFileContext(configX); // configX is not changed,
                                              // is passed down 
   <li> myFContext.create(path, ...);
   <li>...
  </ul>]]>

      <![CDATA[Create a jar file at the given path, containing a manifest with a classpath
 that references all specified entries.
 
 Some platforms may have an upper limit on command line length.  For example,
 the maximum command line length on Windows is 8191 characters, but the
 length of the classpath may exceed this.  To work around this limitation,
 use this method to create a small intermediate jar with a manifest that
 contains the full classpath.  It returns the absolute path to the new jar,
 which the caller may set as the classpath for a new process.
 
 Environment variable evaluation is not supported within a jar manifest, so
 this method expands environment variables before inserting classpath entries
 to the manifest.  The method parses environment variables according to
 platform-specific syntax (%VAR% on Windows, or $VAR otherwise).  On Windows,
 environment variables are case-insensitive.  For example, %VAR% and %var%
 evaluate to the same value.
 
 Specifying the classpath in a jar manifest does not support wildcards, so
 this method expands wildcards internally.  Any classpath entry that ends
 with * is translated to all files at that path with extension .jar or .JAR.
 
 @param inputClassPath String input classpath to bundle into the jar manifest
 @param pwd Path to working directory to save jar
 @param targetDir path to where the jar execution will have its working dir
 @param callerEnv Map<String, String> caller's environment variables to use
   for expansion
 @return String[] with absolute path to new jar in position 0 and
   unexpanded wild card entry path in position 1
 @throws IOException if there is an I/O error while writing the jar file]]>

 Implementations are required to implement thread-safe operations; this may
 be supported by concurrent access to the data, or by using a synchronization
 mechanism to serialize access.

 Not all implementations meet this requirement. Those that do not cannot

    <![CDATA[ViewFs (extends the AbstractFileSystem interface) implements a client-side
 mount table. The viewFs file system is implemented completely in memory on
 the client side. The client-side mount table allows a client to provide a 
 customized view of a file system namespace that is composed from 
 one or more individual file systems (a localFs or Hdfs, S3fs, etc).
 For example one could have a mount table that provides links such as
 <ul>
 <li>  /user          -> hdfs://nnContainingUserDir/user
 <li>  /project/foo   -> hdfs://nnProject1/projects/foo
 <li>  /project/bar   -> hdfs://nnProject2/projects/bar
 <li>  /tmp           -> hdfs://nnTmp/privateTmpForUserXXX
 </ul> 
 
 ViewFs is specified with the following URI: <b>viewfs:///</b> 
 <p>
 To use viewfs one would typically set the default file system in the
 config  (i.e. fs.defaultFS < = viewfs:///) along with the
 mount table config variables as described below. 
 
 <p>
 <b> ** Config variables to specify the mount table entries ** </b>
 <p>
 
 The file system is initialized from the standard Hadoop config through
 config variables.
 See {@link FsConstants} for URI and Scheme constants; 
 See {@link Constants} for config var constants; 
 see {@link ConfigUtil} for convenient lib.
 
 <p>
 All the mount table config entries for view fs are prefixed by 
 <b>fs.viewfs.mounttable.</b>
 For example the above example can be specified with the following
  config variables:
  <ul>
  <li> fs.viewfs.mounttable.default.link./user=
  hdfs://nnContainingUserDir/user
  <li> fs.viewfs.mounttable.default.link./project/foo=
  hdfs://nnProject1/projects/foo
  <li> fs.viewfs.mounttable.default.link./project/bar=
  hdfs://nnProject2/projects/bar
  <li> fs.viewfs.mounttable.default.link./tmp=
  hdfs://nnTmp/privateTmpForUserXXX
  </ul>
  
 The default mount table (when no authority is specified) is 
 from config variables prefixed by <b>fs.viewFs.mounttable.default </b>
 The authority component of a URI can be used to specify a different mount
 table. For example,
 <ul>
 <li>  viewfs://sanjayMountable/
 </ul>
 is initialized from fs.viewFs.mounttable.sanjayMountable.* config variables.
 
  <p> 
  <b> **** Merge Mounts **** </b>(NOTE: merge mounts are not implemented yet.)
  <p>
  
   One can also use "MergeMounts" to merge several directories (this is
   sometimes  called union-mounts or junction-mounts in the literature.
   For example of the home directories are stored on say two file systems
   (because they do not fit on one) then one could specify a mount
   entry such as following merges two dirs:
   <ul>
   <li> /user -> hdfs://nnUser1/user,hdfs://nnUser2/user
   </ul>
  Such a mergeLink can be specified with the following config var where ","
  is used as the separator for each of links to be merged:
  <ul>
  <li> fs.viewfs.mounttable.default.linkMerge./user=
  hdfs://nnUser1/user,hdfs://nnUser1/user
  </ul>
   A special case of the merge mount is where mount table's root is merged
   with the root (slash) of another file system:
   <ul>
   <li>    fs.viewfs.mounttable.default.linkMergeSlash=hdfs://nn99/
   </ul>
   In this cases the root of the mount table is merged with the root of
            <b>hdfs://nn99/ </b>]]>

    <![CDATA[A fencing method is a method by which one node can forcibly prevent
 another node from making continued progress. This might be implemented
 by killing a process on the other node, by denying the other node's
 access to shared storage, or by accessing a PDU to cut the other node's
 power.
 <p>
 Since these methods are often vendor- or device-specific, operators
 may implement this interface in order to achieve fencing.
 <p>
 Fencing is configured by the operator as an ordered list of methods to
 attempt. Each method will be tried in turn, and the next in the list
 will only be attempted if the previous one fails. See {@link NodeFencer}
 for more information.

    <![CDATA[A wrapper for Writable instances.
 <p>
 When two sequence files, which have same Key type but different Value
 types, are mapped out to reduce, multiple Value types is not allowed.
 In this case, this class can help you wrap instances with different types.
 </p>
 
 <p>
 Compared with <code>ObjectWritable</code>, this class is much more effective,
 because <code>ObjectWritable</code> will append the class declaration as a String 
 into the output file in every Key-Value pair.
 </p>
 
 <p>
 Generic Writable implements {@link Configurable} interface, so that it will be 
 configured by the framework. The configuration is passed to the wrapped objects
 implementing {@link Configurable} interface <i>before deserialization</i>. 
 </p>
 
 how to use it: <br>
 1. Write your own class, such as GenericObject, which extends GenericWritable.<br> 
 2. Implements the abstract method <code>getTypes()</code>, defines 
    the classes which will be wrapped in GenericObject in application.
    Attention: this classes defined in <code>getTypes()</code> method, must
    implement <code>Writable</code> interface.
 <br><br>
 
 The code looks like this:
 <blockquote><pre>
 public class GenericObject extends GenericWritable {
 
   private static Class[] CLASSES = {
               ClassType1.class, 
               ClassType2.class,
               ClassType3.class,
               };

   protected Class[] getTypes() {
       return CLASSES;
   }

 }
 </pre></blockquote>

    <![CDATA[<code>SequenceFile</code>s are flat files consisting of binary key/value 
 pairs.
 
 <p><code>SequenceFile</code> provides {@link SequenceFile.Writer},
 {@link SequenceFile.Reader} and {@link Sorter} classes for writing,
 reading and sorting respectively.</p>
 
 There are three <code>SequenceFile</code> <code>Writer</code>s based on the 
 {@link CompressionType} used to compress key/value pairs:
 <ol>
   <li>
   <code>Writer</code> : Uncompressed records.
   </li>
   <li>
   <code>RecordCompressWriter</code> : Record-compressed files, only compress 
                                       values.
   </li>
   <li>
   <code>BlockCompressWriter</code> : Block-compressed files, both keys & 
                                      values are collected in 'blocks' 
                                      separately and compressed. The size of 
                                      the 'block' is configurable.
 </ol>
 
 <p>The actual compression algorithm used to compress key and/or values can be
 specified by using the appropriate {@link CompressionCodec}.</p>
 
 <p>The recommended way is to use the static <tt>createWriter</tt> methods
 provided by the <code>SequenceFile</code> to chose the preferred format.</p>

 <p>The {@link SequenceFile.Reader} acts as the bridge and can read any of the
 above <code>SequenceFile</code> formats.</p>

 <h4 id="Formats">SequenceFile Formats</h4>
 
 <p>Essentially there are 3 different formats for <code>SequenceFile</code>s
 depending on the <code>CompressionType</code> specified. All of them share a
 <a href="#Header">common header</a> described below.
 
 <h5 id="Header">SequenceFile Header</h5>
 <ul>
   <li>
   version - 3 bytes of magic header <b>SEQ</b>, followed by 1 byte of actual 
             version number (e.g. SEQ4 or SEQ6)
   </li>
   <li>
   keyClassName -key class
   </li>
   <li>
   valueClassName - value class
   </li>
   <li>
   compression - A boolean which specifies if compression is turned on for 
                 keys/values in this file.
   </li>
   <li>
   blockCompression - A boolean which specifies if block-compression is 
                      turned on for keys/values in this file.
   </li>
   <li>
   compression codec - <code>CompressionCodec</code> class which is used for  
                       compression of keys and/or values (if compression is 
                       enabled).
   </li>
   <li>
   metadata - {@link Metadata} for this file.
   </li>
   <li>
   sync - A sync marker to denote end of the header.
   </li>
 </ul>
 
 <h5 id="#UncompressedFormat">Uncompressed SequenceFile Format</h5>
 <ul>
 <li>
 <a href="#Header">Header</a>
 </li>
 <li>
 Record
   <ul>
     <li>Record length</li>
     <li>Key length</li>
     <li>Key</li>
     <li>Value</li>
   </ul>
 </li>
 <li>
 A sync-marker every few <code>100</code> bytes or so.
 </li>
 </ul>

 <h5 id="#RecordCompressedFormat">Record-Compressed SequenceFile Format</h5>
 <ul>
 <li>
 <a href="#Header">Header</a>

   <ul>
     <li>Record length</li>
     <li>Key length</li>
     <li>Key</li>
     <li><i>Compressed</i> Value</li>
   </ul>
 </li>
 <li>
 A sync-marker every few <code>100</code> bytes or so.
 </li>
 </ul>
 
 <h5 id="#BlockCompressedFormat">Block-Compressed SequenceFile Format</h5>
 <ul>
 <li>
 <a href="#Header">Header</a>
 </li>
 <li>
 Record <i>Block</i>
   <ul>
     <li>Uncompressed number of records in the block</li>
     <li>Compressed key-lengths block-size</li>
     <li>Compressed key-lengths block</li>
     <li>Compressed keys block-size</li>
     <li>Compressed keys block</li>
     <li>Compressed value-lengths block-size</li>
     <li>Compressed value-lengths block</li>
     <li>Compressed values block-size</li>
     <li>Compressed values block</li>
   </ul>
 </li>
 <li>
 A sync-marker every block.
 </li>
 </ul>
 
 <p>The compressed blocks of key lengths and value lengths consist of the 
 actual lengths of individual keys/values encoded in ZeroCompressedInteger 
 format.</p>

 algorithm.  The configuration parameter
 io.compression.codec.bzip2.library can be used to control this
 behavior.

 In the pure-Java mode, the Compressor and Decompressor interfaces
 are not implemented.  Therefore, in that mode, those methods of
 CompressionCodec which have a Compressor or Decompressor type
 argument, throw UnsupportedOperationException.

 Currently, support for splittability is available only in the

 requested, the pure-Java implementation is used, regardless of the

    <![CDATA[This interface is meant to be implemented by those compression codecs
 which are capable to compress / de-compress a stream starting at any
 arbitrary position.

 Especially the process of de-compressing a stream starting at some arbitrary
 position is challenging.  Most of the codecs are only able to successfully
 de-compress a stream, if they start from the very beginning till the end.
 One of the reasons is the stored state at the beginning of the stream which
 is crucial for de-compression.

 Yet there are few codecs which do not save the whole state at the beginning
 of the stream and hence can be used to de-compress stream starting at any
 arbitrary points.  This interface is meant to be used by such codecs.  Such
 codecs are highly valuable, especially in the context of Hadoop, because
 an input compressed file can be split and hence can be worked on by multiple
 machines in parallel.]]>

    <![CDATA[A TFile is a container of key-value pairs. Both keys and values are type-less
 bytes. Keys are restricted to 64KB, value length is not restricted
 (practically limited to the available disk storage). TFile further provides
 the following features:
 <ul>
 <li>Block Compression.
 <li>Named meta data blocks.
 <li>Sorted or unsorted keys.
 <li>Seek by key or by file offset.
 </ul>
 The memory footprint of a TFile includes the following:
 <ul>
 <li>Some constant overhead of reading or writing a compressed block.
 <ul>
 <li>Each compressed block requires one compression/decompression codec for
 I/O.
 <li>Temporary space to buffer the key.
 <li>Temporary space to buffer the value (for TFile.Writer only). Values are
 chunk encoded, so that we buffer at most one chunk of user data. By default,
 the chunk buffer is 1MB. Reading chunked value does not require additional
 memory.
 </ul>
 <li>TFile index, which is proportional to the total number of Data Blocks.
 The total amount of memory needed to hold the index can be estimated as
 (56+AvgKeySize)*NumBlocks.
 <li>MetaBlock index, which is proportional to the total number of Meta
 Blocks.The total amount of memory needed to hold the index for Meta Blocks
 can be estimated as (40+AvgMetaBlockName)*NumMetaBlock.
 </ul>
 <p>
 The behavior of TFile can be customized by the following variables through
 Configuration:
 <ul>
 <li><b>tfile.io.chunk.size</b>: Value chunk size. Integer (in bytes). Default
 to 1MB. Values of the length less than the chunk size is guaranteed to have
 known value length in read time (See
 {@link TFile.Reader.Scanner.Entry#isValueLengthKnown()}).
 <li><b>tfile.fs.output.buffer.size</b>: Buffer size used for
 FSDataOutputStream. Integer (in bytes). Default to 256KB.
 <li><b>tfile.fs.input.buffer.size</b>: Buffer size used for
 FSDataInputStream. Integer (in bytes). Default to 256KB.
 </ul>
 <p>
 Suggestions on performance optimization.
 <ul>
 <li>Minimum block size. We recommend a setting of minimum block size between
 256KB to 1MB for general usage. Larger block size is preferred if files are
 primarily for sequential access. However, it would lead to inefficient random
 access (because there are more data to decompress). Smaller blocks are good
 for random access, but require more memory to hold the block index, and may
 be slower to create (because we must flush the compressor stream at the
 conclusion of each data block, which leads to an FS I/O flush). Further, due
 to the internal caching in Compression codec, the smallest possible block
 size would be around 20KB-30KB.
 <li>The current implementation does not offer true multi-threading for
 reading. The implementation uses FSDataInputStream seek()+read(), which is
 shown to be much faster than positioned-read call in single thread mode.
 However, it also means that if multiple threads attempt to access the same
 TFile (using multiple scanners) simultaneously, the actual I/O is carried out
 sequentially even if they access different DFS blocks.
 <li>Compression codec. Use "none" if the data is not very compressable (by
 compressable, I mean a compression ratio at least 2:1). Generally, use "lzo"
 as the starting point for experimenting. "gz" overs slightly better
 compression ratio over "lzo" but requires 4x CPU to compress and 2x CPU to
 decompress, comparing to "lzo".
 <li>File system buffering, if the underlying FSDataInputStream and
 FSDataOutputStream is already adequately buffered; or if applications
 reads/writes keys and values in large buffers, we can reduce the sizes of
 input/output buffering in TFile layer by setting the configuration parameters
 "tfile.fs.input.buffer.size" and "tfile.fs.output.buffer.size".
 </ul>
 
 Some design rationale behind TFile can be found at <a

  <![CDATA[This package defines an API for reporting performance metric information.
<p/>
The API is abstract so that it can be implemented on top of
a variety of metrics client libraries.  The choice of 
client library is a configuration option, and different 
modules within the same application can use
different metrics implementation libraries.
<p/>
Sub-packages:
<dl>
    <dt><code>org.apache.hadoop.metrics.spi</code></dt>
    <dd>The abstract Server Provider Interface package. Those wishing to
    integrate the metrics API with a particular metrics client library should 
    extend this package.</dd>
    
    <dt><code>org.apache.hadoop.metrics.file</code></dt>
    <dd>An implementation package which writes the metric data to 
    a file, or sends it to the standard output stream.</dd>
 
    <dt> <code>org.apache.hadoop.metrics.ganglia</code></dt>
    <dd>An implementation package which sends metric data to 
    <a href="http://ganglia.sourceforge.net/">Ganglia</a>.</dd>
</dl>

<h3>Introduction to the Metrics API</h3>

Here is a simple example of how to use this package to report a single
metric value:
<pre>
    private ContextFactory contextFactory = ContextFactory.getFactory();
    
    void reportMyMetric(float myMetric) {
        MetricsContext myContext = contextFactory.getContext("myContext");
        MetricsRecord myRecord = myContext.getRecord("myRecord");
        myRecord.setMetric("myMetric", myMetric);
        myRecord.update();
    }
</pre>
  
In this example there are three names:
<dl>
  <dt><i>myContext</i></dt>
  <dd>The context name will typically identify either the application, or else a
  module within an application or library.</dd>
  
  <dt><i>myRecord</i></dt>
  <dd>The record name generally identifies some entity for which a set of
  metrics are to be reported.  For example, you could have a record named 
  "cacheStats" for reporting a number of statistics relating to the usage of
  some cache in your application.</dd>
  
  <dt><i>myMetric</i></dt>
  <dd>This identifies a particular metric.  For example, you might have metrics
  named "cache_hits" and "cache_misses".
  </dd>
</dl>

<h3>Tags</h3>

In some cases it is useful to have multiple records with the same name. For 
example, suppose that you want to report statistics about each disk on a computer. 
In this case, the record name would be something like "diskStats", but you also
need to identify the disk which is done by adding a <i>tag</i> to the record.
The code could look something like this:
<pre>
    private MetricsRecord diskStats =
            contextFactory.getContext("myContext").getRecord("diskStats");
            
    void reportDiskMetrics(String diskName, float diskBusy, float diskUsed) {
        diskStats.setTag("diskName", diskName);
        diskStats.setMetric("diskBusy", diskBusy);
        diskStats.setMetric("diskUsed", diskUsed);
        diskStats.update();
    }
</pre>

<h3>Buffering and Callbacks</h3>

Data is not sent immediately to the metrics system when 
<code>MetricsRecord.update()</code> is called. Instead it is stored in an
internal table, and the contents of the table are sent periodically.
This can be important for two reasons:
<ol>
    <li>It means that a programmer is free to put calls to this API in an 
    inner loop, since updates can be very frequent without slowing down
    the application significantly.</li>
    <li>Some implementations can gain efficiency by combining many metrics 
    into a single UDP message.</li>
</ol>

The API provides a timer-based callback via the 
<code>registerUpdater()</code> method.  The benefit of this
versus using <code>java.util.Timer</code> is that the callbacks will be done 
immediately before sending the data, making the data as current as possible.

<h3>Configuration</h3>

It is possible to programmatically examine and modify configuration data
before creating a context, like this:
<pre>
    ContextFactory factory = ContextFactory.getFactory();
    ... examine and/or modify factory attributes ...
    MetricsContext context = factory.getContext("myContext");
</pre>
The factory attributes can be examined and modified using the following
<code>ContextFactory</code>methods:
<ul>
    <li><code>Object getAttribute(String attributeName)</code></li>
    <li><code>String[] getAttributeNames()</code></li>
    <li><code>void setAttribute(String name, Object value)</code></li>
    <li><code>void removeAttribute(attributeName)</code></li>
</ul>

<p/>
<code>ContextFactory.getFactory()</code> initializes the factory attributes by
reading the properties file <code>hadoop-metrics.properties</code> if it exists 
on the class path.

<p/>
A factory attribute named:
<pre>
<i>contextName</i>.class
</pre>
should have as its value the fully qualified name of the class to be 
instantiated by a call of the <code>CodeFactory</code> method
<code>getContext(<i>contextName</i>)</code>.  If this factory attribute is not 
specified, the default is to instantiate 
<code>org.apache.hadoop.metrics.file.FileContext</code>.

<p/>
Other factory attributes are specific to a particular implementation of this 
API and are documented elsewhere.  For example, configuration attributes for
the file and Ganglia implementations can be found in the javadoc for 
their respective packages.]]>

 Simple {@link DNSToSwitchMapping} implementation that reads a 2 column text
 file. The columns are separated by whitespace. The first column is a DNS or
 IP address and the second column specifies the rack where the address maps.

 This class uses the configuration parameter {@code
 net.topology.table.file.name} to locate the mapping file.

 Calls to {@link #resolve(List)} will look up the address as defined in the
 mapping file. If no entry corresponding to the address is found, the value
 {@code /default-rack} is returned.

  <h2>Introduction</h2>
  
  Software systems of any significant complexity require mechanisms for data 
interchange with the outside world. These interchanges typically involve the
marshaling and unmarshaling of logical units of data to and from data streams
(files, network connections, memory buffers etc.). Applications usually have
some code for serializing and deserializing the data types that they manipulate
embedded in them. The work of serialization has several features that make
automatic code generation for it worthwhile. Given a particular output encoding
(binary, XML, etc.), serialization of primitive types and simple compositions
of primitives (structs, vectors etc.) is a very mechanical task. Manually
written serialization code can be susceptible to bugs especially when records
have a large number of fields or a record definition changes between software
versions. Lastly, it can be very useful for applications written in different
programming languages to be able to share and interchange data. This can be 
made a lot easier by describing the data records manipulated by these
applications in a language agnostic manner and using the descriptions to derive
implementations of serialization in multiple target languages. 

This document describes Hadoop Record I/O, a mechanism that is aimed 
at
<ul> 
<li> enabling the specification of simple serializable data types (records) 
<li> enabling the generation of code in multiple target languages for
marshaling and unmarshaling such types
<li> providing target language specific support that will enable application 
programmers to incorporate generated code into their applications
</ul>

The goals of Hadoop Record I/O are similar to those of mechanisms such as XDR,
ASN.1, PADS and ICE. While these systems all include a DDL that enables
the specification of most record types, they differ widely in what else they
focus on. The focus in Hadoop Record I/O is on data marshaling and
multi-lingual support.  We take a translator-based approach to serialization.
Hadoop users have to describe their data in a simple data description
language. The Hadoop DDL translator rcc generates code that users
can invoke in order to read/write their data from/to simple stream 
abstractions. Next we list explicitly some of the goals and non-goals of
Hadoop Record I/O.


<h3>Goals</h3>

<ul>
<li> Support for commonly used primitive types. Hadoop should include as
primitives commonly used builtin types from programming languages we intend to
support.

<li> Support for common data compositions (including recursive compositions).
Hadoop should support widely used composite types such as structs and
vectors.

<li> Code generation in multiple target languages. Hadoop should be capable of
generating serialization code in multiple target languages and should be
easily extensible to new target languages. The initial target languages are
C++ and Java.

<li> Support for generated target languages. Hadooop should include support
in the form of headers, libraries, packages for supported target languages 
that enable easy inclusion and use of generated code in applications.

<li> Support for multiple output encodings. Candidates include
packed binary, comma-separated text, XML etc.

<li> Support for specifying record types in a backwards/forwards compatible
manner. This will probably be in the form of support for optional fields in
records. This version of the document does not include a description of the
planned mechanism, we intend to include it in the next iteration.

</ul>

<h3>Non-Goals</h3>

<ul>
  <li> Serializing existing arbitrary C++ classes.
  <li> Serializing complex data structures such as trees, linked lists etc.
  <li> Built-in indexing schemes, compression, or check-sums.
  <li> Dynamic construction of objects from an XML schema.
</ul>

The remainder of this document describes the features of Hadoop record I/O
in more detail. Section 2 describes the data types supported by the system.
Section 3 lays out the DDL syntax with some examples of simple records. 
Section 4 describes the process of code generation with rcc. Section 5
describes target language mappings and support for Hadoop types. We include a
fairly complete description of C++ mappings with intent to include Java and
others in upcoming iterations of this document. The last section talks about
supported output encodings.


<h2>Data Types and Streams</h2>

This section describes the primitive and composite types supported by Hadoop.
We aim to support a set of types that can be used to simply and efficiently
express a wide range of record types in different programming languages.

<h3>Primitive Types</h3>

For the most part, the primitive types of Hadoop map directly to primitive
types in high level programming languages. Special cases are the
ustring (a Unicode string) and buffer types, which we believe
find wide use and which are usually implemented in library code and not
available as language built-ins. Hadoop also supplies these via library code
when a target language built-in is not present and there is no widely
adopted "standard" implementation. The complete list of primitive types is:

<ul>
  <li> byte: An 8-bit unsigned integer.
  <li> boolean: A boolean value.
  <li> int: A 32-bit signed integer.
  <li> long: A 64-bit signed integer.
  <li> float: A single precision floating point number as described by
    IEEE-754.
  <li> double: A double precision floating point number as described by
    IEEE-754.
  <li> ustring: A string consisting of Unicode characters.
  <li> buffer: An arbitrary sequence of bytes. 
</ul>


<h3>Composite Types</h3>
Hadoop supports a small set of composite types that enable the description
of simple aggregate types and containers. A composite type is serialized
by sequentially serializing it constituent elements. The supported
composite types are:

<ul>

  <li> record: An aggregate type like a C-struct. This is a list of
typed fields that are together considered a single unit of data. A record
is serialized by sequentially serializing its constituent fields. In addition
to serialization a record has comparison operations (equality and less-than)
implemented for it, these are defined as memberwise comparisons.

  <li>vector: A sequence of entries of the same data type, primitive
or composite.

  <li> map: An associative container mapping instances of a key type to
instances of a value type. The key and value types may themselves be primitive
or composite types. 

</ul>

<h3>Streams</h3>

Hadoop generates code for serializing and deserializing record types to
abstract streams. For each target language Hadoop defines very simple input
and output stream interfaces. Application writers can usually develop
concrete implementations of these by putting a one method wrapper around
an existing stream implementation.


<h2>DDL Syntax and Examples</h2>

We now describe the syntax of the Hadoop data description language. This is
followed by a few examples of DDL usage.
 
<h3>Hadoop DDL Syntax</h3>

<pre><code>
recfile = *include module *record
include = "include" path
path = (relative-path / absolute-path)
module = "module" module-name
module-name = name *("." name)
record := "class" name "{" 1*(field) "}"
field := type name ";"
name :=  ALPHA (ALPHA / DIGIT / "_" )*
type := (ptype / ctype)
ptype := ("byte" / "boolean" / "int" |
          "long" / "float" / "double"
          "ustring" / "buffer")
ctype := (("vector" "<" type ">") /
          ("map" "<" type "," type ">" ) ) / name)
</code></pre>

A DDL file describes one or more record types. It begins with zero or
more include declarations, a single mandatory module declaration
followed by zero or more class declarations. The semantics of each of
these declarations are described below:

<ul>

<li>include: An include declaration specifies a DDL file to be
referenced when generating code for types in the current DDL file. Record types
in the current compilation unit may refer to types in all included files.
File inclusion is recursive. An include does not trigger code
generation for the referenced file.

<li> module: Every Hadoop DDL file must have a single module
declaration that follows the list of includes and precedes all record
declarations. A module declaration identifies a scope within which
the names of all types in the current file are visible. Module names are
mapped to C++ namespaces, Java packages etc. in generated code.

<li> class: Records types are specified through class
declarations. A class declaration is like a Java class declaration.
It specifies a named record type and a list of fields that constitute records
of the type. Usage is illustrated in the following examples.

</ul>

<h3>Examples</h3>

<ul>
<li>A simple DDL file links.jr with just one record declaration. 
<pre><code>
module links {
    class Link {
        ustring URL;
        boolean isRelative;
        ustring anchorText;
    };
}
</code></pre>

<li> A DDL file outlinks.jr which includes another
<pre><code>
include "links.jr"

module outlinks {
    class OutLinks {
        ustring baseURL;
        vector<links.Link> outLinks;
    };
}
</code></pre>
</ul>

<h2>Code Generation</h2>

The Hadoop translator is written in Java. Invocation is done by executing a 
wrapper shell script named named rcc. It takes a list of
record description files as a mandatory argument and an
optional language argument (the default is Java) --language or
-l. Thus a typical invocation would look like:
<pre><code>
$ rcc -l C++ <filename> ...
</code></pre>


<h2>Target Language Mappings and Support</h2>

For all target languages, the unit of code generation is a record type. 
For each record type, Hadoop generates code for serialization and
deserialization, record comparison and access to record members.

<h3>C++</h3>

Support for including Hadoop generated C++ code in applications comes in the
form of a header file recordio.hh which needs to be included in source
that uses Hadoop types and a library librecordio.a which applications need
to be linked with. The header declares the Hadoop C++ namespace which defines
appropriate types for the various primitives, the basic interfaces for
records and streams and enumerates the supported serialization encodings.
Declarations of these interfaces and a description of their semantics follow:

<pre><code>
namespace hadoop {

  enum RecFormat { kBinary, kXML, kCSV };

  class InStream {
  public:
    virtual ssize_t read(void *buf, size_t n) = 0;
  };

  class OutStream {
  public:
    virtual ssize_t write(const void *buf, size_t n) = 0;
  };

  class IOError : public runtime_error {
  public:
    explicit IOError(const std::string& msg);
  };

  class IArchive;
  class OArchive;

  class RecordReader {
  public:
    RecordReader(InStream& in, RecFormat fmt);
    virtual ~RecordReader(void);

    virtual void read(Record& rec);
  };

  class RecordWriter {
  public:
    RecordWriter(OutStream& out, RecFormat fmt);
    virtual ~RecordWriter(void);

    virtual void write(Record& rec);
  };


  class Record {
  public:
    virtual std::string type(void) const = 0;
    virtual std::string signature(void) const = 0;
  protected:
    virtual bool validate(void) const = 0;

    virtual void
    serialize(OArchive& oa, const std::string& tag) const = 0;

    virtual void
    deserialize(IArchive& ia, const std::string& tag) = 0;
  };
}
</code></pre>

<ul>

<li> RecFormat: An enumeration of the serialization encodings supported
by this implementation of Hadoop.

<li> InStream: A simple abstraction for an input stream. This has a 
single public read method that reads n bytes from the stream into
the buffer buf. Has the same semantics as a blocking read system
call. Returns the number of bytes read or -1 if an error occurs.

<li> OutStream: A simple abstraction for an output stream. This has a 
single write method that writes n bytes to the stream from the
buffer buf. Has the same semantics as a blocking write system
call. Returns the number of bytes written or -1 if an error occurs.

<li> RecordReader: A RecordReader reads records one at a time from
an underlying stream in a specified record format. The reader is instantiated
with a stream and a serialization format. It has a read method that
takes an instance of a record and deserializes the record from the stream.

<li> RecordWriter: A RecordWriter writes records one at a
time to an underlying stream in a specified record format. The writer is
instantiated with a stream and a serialization format. It has a
write method that takes an instance of a record and serializes the
record to the stream.

<li> Record: The base class for all generated record types. This has two
public methods type and signature that return the typename and the
type signature of the record.

</ul>

Two files are generated for each record file (note: not for each record). If a
record file is named "name.jr", the generated files are 
"name.jr.cc" and "name.jr.hh" containing serialization 
implementations and record type declarations respectively.

For each record in the DDL file, the generated header file will contain a
class definition corresponding to the record type, method definitions for the
generated type will be present in the '.cc' file.  The generated class will
inherit from the abstract class hadoop::Record. The DDL files
module declaration determines the namespace the record belongs to.
Each '.' delimited token in the module declaration results in the
creation of a namespace. For instance, the declaration module docs.links
results in the creation of a docs namespace and a nested 
docs::links namespace. In the preceding examples, the Link class
is placed in the links namespace. The header file corresponding to
the links.jr file will contain:

<pre><code>
namespace links {
  class Link : public hadoop::Record {
    // ....
  };
};
</code></pre>

Each field within the record will cause the generation of a private member
declaration of the appropriate type in the class declaration, and one or more
acccessor methods. The generated class will implement the serialize and
deserialize methods defined in hadoop::Record+. It will also 
implement the inspection methods type and signature from
hadoop::Record. A default constructor and virtual destructor will also
be generated. Serialization code will read/write records into streams that
implement the hadoop::InStream and the hadoop::OutStream interfaces.

For each member of a record an accessor method is generated that returns 
either the member or a reference to the member. For members that are returned 
by value, a setter method is also generated. This is true for primitive 
data members of the types byte, int, long, boolean, float and 
double. For example, for a int field called MyField the folowing
code is generated.

<pre><code>
...
private:
  int32_t mMyField;
  ...
public:
  int32_t getMyField(void) const {
    return mMyField;
  };

  void setMyField(int32_t m) {
    mMyField = m;
  };
  ...
</code></pre>

For a ustring or buffer or composite field. The generated code
only contains accessors that return a reference to the field. A const
and a non-const accessor are generated. For example:

<pre><code>
...
private:
  std::string mMyBuf;
  ...
public:

  std::string& getMyBuf() {
    return mMyBuf;
  };

  const std::string& getMyBuf() const {
    return mMyBuf;
  };
  ...
</code></pre>

<h4>Examples</h4>

Suppose the inclrec.jr file contains:
<pre><code>
module inclrec {
    class RI {
        int      I32;
        double   D;
        ustring  S;
    };
}
</code></pre>

and the testrec.jr file contains:

<pre><code>
include "inclrec.jr"
module testrec {
    class R {
        vector<float> VF;
        RI            Rec;
        buffer        Buf;
    };
}
</code></pre>

Then the invocation of rcc such as:
<pre><code>
$ rcc -l c++ inclrec.jr testrec.jr
</code></pre>
will result in generation of four files:
inclrec.jr.{cc,hh} and testrec.jr.{cc,hh}.

The inclrec.jr.hh will contain:

<pre><code>
#ifndef _INCLREC_JR_HH_
#define _INCLREC_JR_HH_

#include "recordio.hh"

namespace inclrec {
  
  class RI : public hadoop::Record {

  private:

    int32_t      I32;
    double       D;
    std::string  S;

  public:

    RI(void);
    virtual ~RI(void);

    virtual bool operator==(const RI& peer) const;
    virtual bool operator<(const RI& peer) const;

    virtual int32_t getI32(void) const { return I32; }
    virtual void setI32(int32_t v) { I32 = v; }

    virtual double getD(void) const { return D; }
    virtual void setD(double v) { D = v; }

    virtual std::string& getS(void) const { return S; }
    virtual const std::string& getS(void) const { return S; }

    virtual std::string type(void) const;
    virtual std::string signature(void) const;

  protected:

    virtual void serialize(hadoop::OArchive& a) const;
    virtual void deserialize(hadoop::IArchive& a);
  };
} // end namespace inclrec

#endif /* _INCLREC_JR_HH_ */

</code></pre>

The testrec.jr.hh file will contain:


<pre><code>

#ifndef _TESTREC_JR_HH_
#define _TESTREC_JR_HH_

#include "inclrec.jr.hh"

namespace testrec {
  class R : public hadoop::Record {

  private:

    std::vector<float> VF;
    inclrec::RI        Rec;
    std::string        Buf;

  public:

    R(void);
    virtual ~R(void);

    virtual bool operator==(const R& peer) const;
    virtual bool operator<(const R& peer) const;

    virtual std::vector<float>& getVF(void) const;
    virtual const std::vector<float>& getVF(void) const;

    virtual std::string& getBuf(void) const ;
    virtual const std::string& getBuf(void) const;

    virtual inclrec::RI& getRec(void) const;
    virtual const inclrec::RI& getRec(void) const;

    virtual std::string type(void) const;
    virtual std::string signature(void) const;
  };
}; // end namespace testrec
#endif /* _TESTREC_JR_HH_ */

</code></pre>

<h3>Java</h3>

Code generation for Java is similar to that for C++. A Java class is generated
for each record type with private members corresponding to the fields. Getters
and setters for fields are also generated. Some differences arise in the
way comparison is expressed and in the mapping of modules to packages and
classes to files. For equality testing, an equals method is generated
for each record type. As per Java requirements a hashCode method is also
generated. For comparison a compareTo method is generated for each
record type. This has the semantics as defined by the Java Comparable
interface, that is, the method returns a negative integer, zero, or a positive
integer as the invoked object is less than, equal to, or greater than the
comparison parameter.

A .java file is generated per record type as opposed to per DDL
file as in C++. The module declaration translates to a Java
package declaration. The module name maps to an identical Java package
name. In addition to this mapping, the DDL compiler creates the appropriate
directory hierarchy for the package and places the generated .java
files in the correct directories.

<h2>Data encodings</h2>

This section describes the format of the data encodings supported by Hadoop.
Currently, three data encodings are supported, namely binary, CSV and XML.

<h3>Binary Serialization Format</h3>

The binary data encoding format is fairly dense. Serialization of composite
types is simply defined as a concatenation of serializations of the constituent
elements (lengths are included in vectors and maps).

Composite types are serialized as follows:
<ul>
<li> class: Sequence of serialized members.
<li> vector: The number of elements serialized as an int. Followed by a
sequence of serialized elements.
<li> map: The number of key value pairs serialized as an int. Followed
by a sequence of serialized (key,value) pairs.
</ul>

Serialization of primitives is more interesting, with a zero compression
optimization for integral types and normalization to UTF-8 for strings. 
Primitive types are serialized as follows:

<ul>
<li> byte: Represented by 1 byte, as is.
<li> boolean: Represented by 1-byte (0 or 1)
<li> int/long: Integers and longs are serialized zero compressed.
Represented as 1-byte if -120 <= value < 128. Otherwise, serialized as a
sequence of 2-5 bytes for ints, 2-9 bytes for longs. The first byte represents
the number of trailing bytes, N, as the negative number (-120-N). For example,
the number 1024 (0x400) is represented by the byte sequence 'x86 x04 x00'.
This doesn't help much for 4-byte integers but does a reasonably good job with
longs without bit twiddling.
<li> float/double: Serialized in IEEE 754 single and double precision
format in network byte order. This is the format used by Java.
<li> ustring: Serialized as 4-byte zero compressed length followed by
data encoded as UTF-8. Strings are normalized to UTF-8 regardless of native
language representation.
<li> buffer: Serialized as a 4-byte zero compressed length followed by the
raw bytes in the buffer.
</ul>


<h3>CSV Serialization Format</h3>

The CSV serialization format has a lot more structure than the "standard"
Excel CSV format, but we believe the additional structure is useful because

<ul>
<li> it makes parsing a lot easier without detracting too much from legibility
<li> the delimiters around composites make it obvious when one is reading a
sequence of Hadoop records
</ul>

Serialization formats for the various types are detailed in the grammar that
follows. The notable feature of the formats is the use of delimiters for 
indicating the certain field types.

<ul>
<li> A string field begins with a single quote (').
<li> A buffer field begins with a sharp (#).
<li> A class, vector or map begins with 's{', 'v{' or 'm{' respectively and
ends with '}'.
</ul>

The CSV format can be described by the following grammar:

<pre><code>
record = primitive / struct / vector / map
primitive = boolean / int / long / float / double / ustring / buffer

boolean = "T" / "F"
int = ["-"] 1*DIGIT
long = ";" ["-"] 1*DIGIT
float = ["-"] 1*DIGIT "." 1*DIGIT ["E" / "e" ["-"] 1*DIGIT]
double = ";" ["-"] 1*DIGIT "." 1*DIGIT ["E" / "e" ["-"] 1*DIGIT]

ustring = "'" *(UTF8 char except NULL, LF, % and , / "%00" / "%0a" / "%25" / "%2c" )

buffer = "#" *(BYTE except NULL, LF, % and , / "%00" / "%0a" / "%25" / "%2c" )

struct = "s{" record *("," record) "}"
vector = "v{" [record *("," record)] "}"
map = "m{" [*(record "," record)] "}"
</code></pre>

<h3>XML Serialization Format</h3>

The XML serialization format is the same used by Apache XML-RPC
(http://ws.apache.org/xmlrpc/types.html). This is an extension of the original
XML-RPC format and adds some additional data types. All record I/O types are
not directly expressible in this format, and access to a DDL is required in
order to convert these to valid types. All types primitive or composite are
represented by &lt;value&gt; elements. The particular XML-RPC type is
indicated by a nested element in the &lt;value&gt; element. The encoding for
records is always UTF-8. Primitive types are serialized as follows:

<ul>
<li> byte: XML tag &lt;ex:i1&gt;. Values: 1-byte unsigned 
integers represented in US-ASCII
<li> boolean: XML tag &lt;boolean&gt;. Values: "0" or "1"
<li> int: XML tags &lt;i4&gt; or &lt;int&gt;. Values: 4-byte
signed integers represented in US-ASCII.
<li> long: XML tag &lt;ex:i8&gt;. Values: 8-byte signed integers
represented in US-ASCII.
<li> float: XML tag &lt;ex:float&gt;. Values: Single precision
floating point numbers represented in US-ASCII.
<li> double: XML tag &lt;double&gt;. Values: Double precision
floating point numbers represented in US-ASCII.
<li> ustring: XML tag &lt;;string&gt;. Values: String values
represented as UTF-8. XML does not permit all Unicode characters in literal
data. In particular, NULLs and control chars are not allowed. Additionally,
XML processors are required to replace carriage returns with line feeds and to
replace CRLF sequences with line feeds. Programming languages that we work
with do not impose these restrictions on string types. To work around these
restrictions, disallowed characters and CRs are percent escaped in strings.
The '%' character is also percent escaped.
<li> buffer: XML tag &lt;string&&gt;. Values: Arbitrary binary
data. Represented as hexBinary, each byte is replaced by its 2-byte
hexadecimal representation.
</ul>

Composite types are serialized as follows:

<ul>
<li> class: XML tag &lt;struct&gt;. A struct is a sequence of
&lt;member&gt; elements. Each &lt;member&gt; element has a &lt;name&gt;
element and a &lt;value&gt; element. The &lt;name&gt; is a string that must
match /[a-zA-Z][a-zA-Z0-9_]*/. The value of the member is represented
by a &lt;value&gt; element.

<li> vector: XML tag &lt;array&lt;. An &lt;array&gt; contains a
single &lt;data&gt; element. The &lt;data&gt; element is a sequence of
&lt;value&gt; elements each of which represents an element of the vector.

<li> map: XML tag &lt;array&gt;. Same as vector.

</ul>

For example:

<pre><code>
class {
  int           MY_INT;            // value 5
  vector<float> MY_VEC;            // values 0.1, -0.89, 2.45e4
  buffer        MY_BUF;            // value '\00\n\tabc%'
}
</code></pre>

is serialized as

<pre><code class="XML">
&lt;value&gt;
  &lt;struct&gt;
    &lt;member&gt;
      &lt;name&gt;MY_INT&lt;/name&gt;
      &lt;value&gt;&lt;i4&gt;5&lt;/i4&gt;&lt;/value&gt;
    &lt;/member&gt;
    &lt;member&gt;
      &lt;name&gt;MY_VEC&lt;/name&gt;
      &lt;value&gt;
        &lt;array&gt;
          &lt;data&gt;
            &lt;value&gt;&lt;ex:float&gt;0.1&lt;/ex:float&gt;&lt;/value&gt;
            &lt;value&gt;&lt;ex:float&gt;-0.89&lt;/ex:float&gt;&lt;/value&gt;
            &lt;value&gt;&lt;ex:float&gt;2.45e4&lt;/ex:float&gt;&lt;/value&gt;
          &lt;/data&gt;
        &lt;/array&gt;
      &lt;/value&gt;
    &lt;/member&gt;
    &lt;member&gt;
      &lt;name&gt;MY_BUF&lt;/name&gt;
      &lt;value&gt;&lt;string&gt;%00\n\tabc%25&lt;/string&gt;&lt;/value&gt;
    &lt;/member&gt;
  &lt;/struct&gt;
&lt;/value&gt;

    <![CDATA[Implements a <i>Bloom filter</i>, as defined by Bloom in 1970.
 <p>
 The Bloom filter is a data structure that was introduced in 1970 and that has been adopted by 
 the networking research community in the past decade thanks to the bandwidth efficiencies that it
 offers for the transmission of set membership information between networked hosts.  A sender encodes 
 the information into a bit vector, the Bloom filter, that is more compact than a conventional 
 representation. Computation and space costs for construction are linear in the number of elements.  
 The receiver uses the filter to test whether various elements are members of the set. Though the 
 filter will occasionally return a false positive, it will never return a false negative. When creating 
 the filter, the sender can choose its desired point in a trade-off between the false positive rate and the size.

 key more than 15 times will cause an overflow at all filter positions

 A counting Bloom filter is an improvement to standard a Bloom filter as it
 allows dynamic additions and deletions of set membership information.  This 
 is achieved through the use of a counting vector instead of a bit vector.

    <![CDATA[Implements a <i>dynamic Bloom filter</i>, as defined in the INFOCOM 2006 paper.
 <p>
 A dynamic Bloom filter (DBF) makes use of a <code>s * m</code> bit matrix but
 each of the <code>s</code> rows is a standard Bloom filter. The creation 
 process of a DBF is iterative. At the start, the DBF is a <code>1 * m</code>
 bit matrix, i.e., it is composed of a single standard Bloom filter.
 It assumes that <code>n<sub>r</sub></code> elements are recorded in the 
 initial bit vector, where <code>n<sub>r</sub> <= n</code> (<code>n</code> is
 the cardinality of the set <code>A</code> to record in the filter).  
 <p>
 As the size of <code>A</code> grows during the execution of the application,
 several keys must be inserted in the DBF.  When inserting a key into the DBF,
 one must first get an active Bloom filter in the matrix.  A Bloom filter is
 active when the number of recorded keys, <code>n<sub>r</sub></code>, is 
 strictly less than the current cardinality of <code>A</code>, <code>n</code>.
 If an active Bloom filter is found, the key is inserted and 
 <code>n<sub>r</sub></code> is incremented by one. On the other hand, if there
 is no active Bloom filter, a new one is created (i.e., a new row is added to
 the matrix) according to the current size of <code>A</code> and the element
 is added in this new Bloom filter and the <code>n<sub>r</sub></code> value of
 this new Bloom filter is set to one.  A given key is said to belong to the
 DBF if the <code>k</code> positions are set to one in one of the matrix rows.
