-* [HADOOP-3382](https://issues.apache.org/jira/browse/HADOOP-3382) | *Blocker* | **Memory leak when files are not cleanly closed**
+* [HADOOP-1593](https://issues.apache.org/jira/browse/HADOOP-1593) | *Major* | **FsShell should work with paths in non-default FileSystem**
 
-Fixed a memory leak associated with 'abandoned' files (i.e. not cleanly closed). This held up significant amounts of memory depending on activity and how long NameNode has been running.
+This bug allows non default path to specifeid in fsshell commands.
+
+So, you can now specify hadoop dfs -ls hdfs://remotehost1:port/path
+  and  hadoop dfs -ls hdfs://remotehost2:port/path without changing the config.

-* [HADOOP-3266](https://issues.apache.org/jira/browse/HADOOP-3266) | *Major* | **Remove HOD changes from CHANGES.txt, as they are now inside src/contrib/hod**
+* [HADOOP-2178](https://issues.apache.org/jira/browse/HADOOP-2178) | *Major* | **Job history on HDFS**
 
-Moved HOD change items from CHANGES.txt to a new file src/contrib/hod/CHANGES.txt.
+This feature provides facility to store job history on DFS. Now cluster admin can provide either localFS location or DFS location using configuration property "mapred.job.history.location"  to store job histroy. History will be logged in user specified location also. User can specify history location using configuration property "mapred.job.history.user.location" .
+The classes org.apache.hadoop.mapred.DefaultJobHistoryParser.MasterIndex and org.apache.hadoop.mapred.DefaultJobHistoryParser.MasterIndexParseListener, and public method org.apache.hadoop.mapred.DefaultJobHistoryParser.parseMasterIndex are not available.
+The signature of public method org.apache.hadoop.mapred.DefaultJobHistoryParser.parseJobTasks(File jobHistoryFile, JobHistory.JobInfo job) is changed to DefaultJobHistoryParser.parseJobTasks(String jobHistoryFile, JobHistory.JobInfo job, FileSystem fs).
+The signature of public method org.apache.hadoop.mapred.JobHistory.parseHistory(File path, Listener l) is changed to JobHistory.parseHistoryFromFS(String path, Listener l, FileSystem fs)

-* [HADOOP-3168](https://issues.apache.org/jira/browse/HADOOP-3168) | *Major* | **reduce amount of logging in hadoop streaming**
+* [HADOOP-1985](https://issues.apache.org/jira/browse/HADOOP-1985) | *Major* | **Abstract node to switch mapping into a topology service class used by namenode and jobtracker**
 
-Decreases the frequency of logging from streaming from every 100 records to every 10,000 records.
+This issue introduces rack awareness for map tasks. It also moves the rack resolution logic to the central servers - NameNode & JobTracker. The administrator can specify a loadable class given by topology.node.switch.mapping.impl to specify the class implementing the logic for rack resolution. The class must implement a method - resolve(List\<String\> names), where names is the list of DNS-names/IP-addresses that we want resolved. The return value is a list of resolved network paths of the form /foo/rack, where rack is the rackID where the node belongs to and foo is the switch where multiple racks are connected, and so on. The default implementation of this class is packaged along with hadoop and points to org.apache.hadoop.net.ScriptBasedMapping and this class loads a script that can be used for rack resolution. The script location is configurable. It is specified by topology.script.file.name and defaults to an empty script. In the case where the script name is empty, /default-rack is returned for all dns-names/IP-addresses. The loadable topology.node.switch.mapping.impl provides administrators fleixibilty to define how their site's node resolution should happen.
+For mapred, one can also specify the level of the cache w.r.t the number of levels in the resolved network path - defaults to two. This means that the JobTracker will cache tasks at the host level and at the rack level.
+Known issue: the task caching will not work with levels greater than 2 (beyond racks). This bug is tracked in HADOOP-3296.

-* [HADOOP-3162](https://issues.apache.org/jira/browse/HADOOP-3162) | *Blocker* | **Map/reduce stops working with comma separated input paths**
+* [HADOOP-1986](https://issues.apache.org/jira/browse/HADOOP-1986) | *Major* | **Add support for a general serialization mechanism for Map Reduce**
 
-The public methods org.apache.hadoop.mapred.JobConf.setInputPath(Path) and org.apache.hadoop.mapred.JobConf.addInputPath(Path) are deprecated. And the methods have the semantics of branch 0.16.
-The following public APIs  are added in org.apache.hadoop.mapred.FileInputFormat :
-public static void setInputPaths(JobConf job, Path... paths);
-public static void setInputPaths(JobConf job, String commaSeparatedPaths);
-public static void addInputPath(JobConf job, Path path);
-public static void addInputPaths(JobConf job, String commaSeparatedPaths);
-Earlier code calling JobConf.setInputPath(Path), JobConf.addInputPath(Path) should now call FileInputFormat.setInputPaths(JobConf, Path...) and FileInputFormat.addInputPath(Path) respectively
+Programs that implement the raw Mapper or Reducer interfaces will need modification to compile with this release. For example,
 
+class MyMapper implements Mapper {
+  public void map(WritableComparable key, Writable val,
+    OutputCollector out, Reporter reporter) throws IOException {
+    // ...
+  }
+  // ...
+}
 
----
+will need to be changed to refer to the parameterized type. For example:
 
-* [HADOOP-3152](https://issues.apache.org/jira/browse/HADOOP-3152) | *Minor* | **Make index interval configuable when using MapFileOutputFormat for map-reduce job**
+class MyMapper implements Mapper\<WritableComparable, Writable, WritableComparable, Writable\> {
+  public void map(WritableComparable key, Writable val,
+    OutputCollector\<WritableComparable, Writable\> out, Reporter reporter) throws IOException {
+    // ...
+  }
+  // ...
+}
 
-Add a static method MapFile#setIndexInterval(Configuration, int interval) so that MapReduce jobs that use MapFileOutputFormat can set the index interval.
+Similarly implementations of the following raw interfaces will need modification: InputFormat, OutputCollector, OutputFormat, Partitioner, RecordReader, RecordWriter

-* [HADOOP-3140](https://issues.apache.org/jira/browse/HADOOP-3140) | *Major* | **JobTracker should not try to promote a (map) task if it does not write to DFS at all**
+* [HADOOP-910](https://issues.apache.org/jira/browse/HADOOP-910) | *Major* | **Reduces can do merges for the on-disk map output files in parallel with their copying**
 
-Tasks that don't generate any output are not inserted in the commit queue of the JobTracker. They are marked as SUCCESSFUL by the TaskTracker and the JobTracker updates their state short-circuiting the commit queue.
+Reducers now perform merges of shuffle data (both in-memory and on disk) while fetching map outputs. Earlier, during shuffle they used to merge only the in-memory outputs.

+* [HADOOP-2219](https://issues.apache.org/jira/browse/HADOOP-2219) | *Major* | **du like command to count number of files under a given directory**
 
-Build script was changed to make HOD versions follow Hadoop version numbers. As a result of this change, the next version of HOD would not be 0.5, but would be synchronized to the Hadoop version number. Users who rely on the version number of HOD should note the unexpected jump in version numbers.
+Added a new fs command fs -count for counting the number of bytes, files and directories under a given path.
+
+Added a new RPC getContentSummary(String path) to ClientProtocol.

+* [HADOOP-2819](https://issues.apache.org/jira/browse/HADOOP-2819) | *Major* | **Remove deprecated methods in JobConf()**
 
-Added a new option -p to distcp for preserving file/directory status.
--p[rbugp]              Preserve status
-                       r: replication number
-                       b: block size
-                       u: user
-                       g: group
-                       p: permission
-                       -p alone is equivalent to -prbugp
+The following deprecated methods are removed from org.apache.hadoop.JobConf :
+public Class getInputKeyClass()
+public void setInputKeyClass(Class theClass)
+public Class getInputValueClass()
+public void setInputValueClass(Class theClass)
+
+The methods, public boolean org.apache.hadoop.JobConf.getSpeculativeExecution() and
+public void org.apache.hadoop.JobConf.setSpeculativeExecution(boolean speculativeExecution) are undeprecated.

-* [HADOOP-3060](https://issues.apache.org/jira/browse/HADOOP-3060) | *Major* | **MiniMRCluster is ignoring parameter taskTrackerFirst**
+* [HADOOP-771](https://issues.apache.org/jira/browse/HADOOP-771) | *Major* | **Namenode should return error when trying to delete non-empty directory**
 
-The parameter boolean taskTrackerFirst is removed from org.apache.hadoop.mapred.MiniMRCluster constructors.
-Thus signature of following APIs
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, boolean taskTrackerFirst, int numDir)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, boolean taskTrackerFirst, int numDir, String[] racks)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, boolean taskTrackerFirst, int numDir, String[] racks, String[] hosts)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, boolean taskTrackerFirst, int numDir, String[] racks, String[] hosts, UnixUserGroupInformation ugi )
-is changed to
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, int numDir)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, int numDir, String[] racks)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, int numDir, String[] racks, String[] hosts)
-  public MiniMRCluster(int jobTrackerPort, int taskTrackerPort, int numTaskTrackers, String namenode, int numDir, String[] racks, String[] hosts, UnixUserGroupInformation ugi )
-respectively.
-Since the old signatures were not deprecated, any code using the old constructors must be changed to use the new constructors.
+This patch adds a new api to file system i.e delete(path, boolean), deprecating the previous delete(path).
+the new api recursively deletes files only if boolean is set to true.
+If path is a file, the boolean value does not matter, if path is a directory and the directory is non empty delete(path, false) will throw an exception and delete(path, true) will delete all files recursively.

-* [HADOOP-3048](https://issues.apache.org/jira/browse/HADOOP-3048) | *Blocker* | **Stringifier**
+* [HADOOP-2765](https://issues.apache.org/jira/browse/HADOOP-2765) | *Major* | **setting memory limits for tasks**
 
- A new Interface and a default implementation to convert and restore serializations of objects to strings.
+This feature enables specifying ulimits for streaming/pipes tasks. Now pipes and streaming tasks have same virtual memory available as the java process which invokes them. Ulimit value will be the same as -Xmx value for java processes provided using mapred.child.java.opts.

-* [HADOOP-3041](https://issues.apache.org/jira/browse/HADOOP-3041) | *Blocker* | **Within a task, the value ofJobConf.getOutputPath() method is modified**
+* [HADOOP-2657](https://issues.apache.org/jira/browse/HADOOP-2657) | *Major* | **Enhancements to DFSClient to support flushing data at any point in time**
 
-1. Deprecates JobConf.setOutputPath and JobConf.getOutputPath
-JobConf.getOutputPath() still returns the same value that it used to return. 
-2. Deprecates OutputFormatBase. Adds FileOutputFormat. Existing output formats extending OutputFormatBase, now extend FileOutputFormat.
-3. Adds the following APIs in FileOutputFormat :
-public static void setOutputPath(JobConf conf, Path outputDir); // sets mapred.output.dir
-public static Path getOutputPath(JobConf conf) ; // gets mapred.output.dir
-public static Path getWorkOutputPath(JobConf conf); // gets mapred.work.output.dir
-4. static void setWorkOutputPath(JobConf conf, Path outputDir) is also added to FileOutputFormat. This is used by the framework to set mapred.work.output.dir as task's temporary output dir .
+A new API DFSOututStream.flush() flushes all outstanding data to the pipeline of datanodes.

-* [HADOOP-3040](https://issues.apache.org/jira/browse/HADOOP-3040) | *Major* | **Streaming should assume an empty key if the first character on a line is the seperator (stream.map.output.field.separator, by default, tab)**
+* [HADOOP-2399](https://issues.apache.org/jira/browse/HADOOP-2399) | *Major* | **Input key and value to combiner and reducer should be reused**
 
-If the first character on a line is the separator, empty key is assumed, and the whole line is the value (due to a bug this was not the case).
+The key and value objects that are given to the Combiner and Reducer are now reused between calls. This is much more efficient, but the user can not assume the objects are constant.

-* [HADOOP-3001](https://issues.apache.org/jira/browse/HADOOP-3001) | *Blocker* | **FileSystems should track how many bytes are read and written**
+* [HADOOP-2423](https://issues.apache.org/jira/browse/HADOOP-2423) | *Major* | **The codes in FSDirectory.mkdirs(...) is inefficient.**
 
-Adds new framework map/reduce counters that track the number of bytes read and written to HDFS, local, KFS, and S3 file systems.
+Improved FSDirectory.mkdirs(...) performance.  In NNThroughputBenchmark-create, the ops per sec in  was improved ~54%.

-This issue introduces rack awareness for map tasks. It also moves the rack resolution logic to the central servers - NameNode & JobTracker. The administrator can specify a loadable class given by topology.node.switch.mapping.impl to specify the class implementing the logic for rack resolution. The class must implement a method - resolve(List\<String\> names), where names is the list of DNS-names/IP-addresses that we want resolved. The return value is a list of resolved network paths of the form /foo/rack, where rack is the rackID where the node belongs to and foo is the switch where multiple racks are connected, and so on. The default implementation of this class is packaged along with hadoop and points to org.apache.hadoop.net.ScriptBasedMapping and this class loads a script that can be used for rack resolution. The script location is configurable. It is specified by topology.script.file.name and defaults to an empty script. In the case where the script name is empty, /default-rack is returned for all dns-names/IP-addresses. The loadable topology.node.switch.mapping.impl provides administrators fleixibilty to define how their site's node resolution should happen.
-For mapred, one can also specify the level of the cache w.r.t the number of levels in the resolved network path - defaults to two. This means that the JobTracker will cache tasks at the host level and at the rack level. 
-Known issue: the task caching will not work with levels greater than 2 (beyond racks). This bug is tracked in HADOOP-3296.
+getFileInfo returns null for File not found instead of throwing FileNotFoundException

-* [HADOOP-1622](https://issues.apache.org/jira/browse/HADOOP-1622) | *Major* | **Hadoop should provide a way to allow the user to specify jar file(s) the user job depends on**
+* [HADOOP-3162](https://issues.apache.org/jira/browse/HADOOP-3162) | *Blocker* | **Map/reduce stops working with comma separated input paths**
+
+The public methods org.apache.hadoop.mapred.JobConf.setInputPath(Path) and org.apache.hadoop.mapred.JobConf.addInputPath(Path) are deprecated. And the methods have the semantics of branch 0.16.
+The following public APIs  are added in org.apache.hadoop.mapred.FileInputFormat :
+public static void setInputPaths(JobConf job, Path... paths);
+public static void setInputPaths(JobConf job, String commaSeparatedPaths);
+public static void addInputPath(JobConf job, Path path);
+public static void addInputPaths(JobConf job, String commaSeparatedPaths);
+Earlier code calling JobConf.setInputPath(Path), JobConf.addInputPath(Path) should now call FileInputFormat.setInputPaths(JobConf, Path...) and FileInputFormat.addInputPath(Path) respectively
 
-This patch allows new command line options for 
 
-hadoop jar 
-which are 
+---
 
-hadoop jar -files \<comma seperated list of files\> -libjars \<comma seperated list of jars\> -archives \<comma seperated list of archives\>
+* [HADOOP-3124](https://issues.apache.org/jira/browse/HADOOP-3124) | *Major* | **DFS data node should not use hard coded 10 minutes as write timeout.**
 
--files options allows you to speficy comma seperated list of path which would be present in your current working directory of your task
--libjars option allows you to add jars to the classpaths of the maps and reduces. 
--archives allows you to pass archives as arguments that are unzipped/unjarred and a link with name of the jar/zip are created in the current working directory if tasks.
+Makes DataNode socket write timeout configurable. User impact : none.

-* [HADOOP-1593](https://issues.apache.org/jira/browse/HADOOP-1593) | *Major* | **FsShell should work with paths in non-default FileSystem**
-
-This bug allows non default path to specifeid in fsshell commands.
+* [HADOOP-3266](https://issues.apache.org/jira/browse/HADOOP-3266) | *Major* | **Remove HOD changes from CHANGES.txt, as they are now inside src/contrib/hod**
 
-So, you can now specify hadoop dfs -ls hdfs://remotehost1:port/path 
-  and  hadoop dfs -ls hdfs://remotehost2:port/path without changing the config.
+Moved HOD change items from CHANGES.txt to a new file src/contrib/hod/CHANGES.txt.

-* [HADOOP-910](https://issues.apache.org/jira/browse/HADOOP-910) | *Major* | **Reduces can do merges for the on-disk map output files in parallel with their copying**
+* [HADOOP-3280](https://issues.apache.org/jira/browse/HADOOP-3280) | *Blocker* | **virtual address space limits break streaming apps**
 
-Reducers now perform merges of shuffle data (both in-memory and on disk) while fetching map outputs. Earlier, during shuffle they used to merge only the in-memory outputs.
+This patch adds the mapred.child.ulimit to limit the virtual memory for children processes to the given value.
 
 
 ---
 
-* [HADOOP-771](https://issues.apache.org/jira/browse/HADOOP-771) | *Major* | **Namenode should return error when trying to delete non-empty directory**
+* [HADOOP-3382](https://issues.apache.org/jira/browse/HADOOP-3382) | *Blocker* | **Memory leak when files are not cleanly closed**
 
-This patch adds a new api to file system i.e delete(path, boolean), deprecating the previous delete(path). 
-the new api recursively deletes files only if boolean is set to true. 
-If path is a file, the boolean value does not matter, if path is a directory and the directory is non empty delete(path, false) will throw an exception and delete(path, true) will delete all files recursively.
+Fixed a memory leak associated with 'abandoned' files (i.e. not cleanly closed). This held up significant amounts of memory depending on activity and how long NameNode has been running.

-* [HADOOP-3837](https://issues.apache.org/jira/browse/HADOOP-3837) | *Major* | **hadop streaming does not use progress reporting to detect hung tasks**
+* [HADOOP-2585](https://issues.apache.org/jira/browse/HADOOP-2585) | *Major* | **Automatic namespace recovery from the secondary image.**
 
-Changed streaming tasks to adhere to task timeout value specified in the job configuration.
+Improved management of replicas of the name space image. If all replicas on the Name Node are lost, the latest check point can be loaded from the secondary Name Node. Use parameter "-importCheckpoint" and specify the location with "fs.checkpoint.dir." The directory structure on the secondary Name Node has changed to match the primary Name Node.

-Modified HOD to include the RPC port of the JobTracker in the 'notes' attribute of the resource manager. The RPC port is included as the string 'Mapred RPC Port:\<port number\>'. Tools that depend on the value of the notes attribute must change to parse this new value.
+Changed fsck to ignore files opened for writing. Introduced new option "-openforwrite" to explicitly show open files.

If the wrappedStream in FSDataOutputStream is Syncalbe, calling FSDataOutputStream.sync() is equivalent to call wrappedStream.sync().  Otherwise, FSDataOutputStream.sync() is a no-op.  Both DistributedFileSystem and LocalFileSystem support the sync() operation.
+Changed exit status of fsck to report whether the files system is healthy or corrupt.

-* [HADOOP-3164](https://issues.apache.org/jira/browse/HADOOP-3164) | *Major* | **Use FileChannel.transferTo() when data is read from DataNode.**
+* [HADOOP-1328](https://issues.apache.org/jira/browse/HADOOP-1328) | *Major* | **Hadoop Streaming needs to provide a way for the stream plugin to update global counters**
 
-Changed data node to use FileChannel.tranferTo() to transfer block data.
+Introduced a way for a streaming process to update global counters and status using stderr stream to emit information. Use "reporter:counter:\<group\>,\<counter\>,\<amount\> " to update a counter. Use "reporter:status:\<message\>" to update status.

-Withdrew the upgrade-to-CRC facility. HDFS will no longer support upgrades from versions without CRCs for block data. Users upgrading from version 0.13 or earlier must first upgrade to an intermediate (0.14, 0.15, 0.16, 0.17) version before doing upgrade to version 0.18 or later.
+Changed job submission protocol to not allow submission if the client's value of mapred.system.dir does not match the job tracker's. Deprecated JobConf.getSystemDir(); use JobClient.getSystemDir().
 
 
 ---
 
-* [HADOOP-2703](https://issues.apache.org/jira/browse/HADOOP-2703) | *Minor* | **New files under lease (before close) still shows up as MISSING files/blocks in fsck**
+* [HADOOP-3460](https://issues.apache.org/jira/browse/HADOOP-3460) | *Minor* | **SequenceFileAsBinaryOutputFormat**

-GenericOptionsParser in branch 0.20 depends on commons-cli2. This jira removes the dependency of branch 0.20 on commons-cli2 completely. The problem is seen after 'ant binary' where all the library files are copied to '$hadoop-home/lib' which already has commons-cli2.
+This patch resets the variable totalBytesProcessed before the final merge sothat it will be used for calculating the progress of reducePhase(the 3rd phase of reduce task) correctly.

-
-Job initialization process was changed to not change (run) states during initialization. The reason is two fold
-- this can lead to deadlock as state changes require circular locking (i.e JobInProgress requires JobTracker lock)
-- events were not raised as these state changes were not informed/propogated back to the JobTracker

-Now the JobTracker takes care of initializing/failing/killing the job and raising appropriate events. The simple rule that was enforced was that "The JobTracker lock is \*must\* before changing the run-state of a job".
+Multithreaded mapper was modified to create a new Runtime exception (object) from a throwable instead of casting a throwable into a RuntimeException, once the Multithreaded map encounters a fault.

-Multithreaded mapper was modified to create a new Runtime exception (object) from a throwable instead of casting a throwable into a RuntimeException, once the Multithreaded map encounters a fault.
+Fixed a bug in the way commit of task outputs happens. The bug was that if commit fails with IOException, the task would be declared as successful.

-* [MAPREDUCE-767](https://issues.apache.org/jira/browse/MAPREDUCE-767) | *Major* | **to remove mapreduce dependency on commons-cli2**
+* [MAPREDUCE-805](https://issues.apache.org/jira/browse/MAPREDUCE-805) | *Major* | **Deadlock in Jobtracker**
 
-Removes the dependency of hadoop-mapred from commons-cli2 and uses commons-cli1.2 for command-line parsing.
+Job initialization process was changed to not change (run) states during initialization. The reason is two fold
+- this can lead to deadlock as state changes require circular locking (i.e JobInProgress requires JobTracker lock)
+- events were not raised as these state changes were not informed/propogated back to the JobTracker
+
+Now the JobTracker takes care of initializing/failing/killing the job and raising appropriate events. The simple rule that was enforced was that "The JobTracker lock is \*must\* before changing the run-state of a job".

+* [MAPREDUCE-832](https://issues.apache.org/jira/browse/MAPREDUCE-832) | *Major* | **Too many WARN messages about deprecated memorty config variables in JobTacker log**
 
-JobTracker was changed to take an identifier as an argument. This helps in testcases where the jobtracker/mapred-cluster is (re)started in a short span of time and the chances of jobtracker identifier clashing are high. Also the RecoveryManager was modified to throw an exception if a job fails in init during the recovery process. The reason being that this event will trigger a job failure in the recovery process and will remove the failed job from further initialization and processing.
+Reduced the frequency of log messages printed when a deprecated memory management variable is found in configuration of a job.

+* [MAPREDUCE-834](https://issues.apache.org/jira/browse/MAPREDUCE-834) | *Major* | **When TaskTracker config use old memory management values its memory monitoring is diabled.**
 
-Various code paths in the framework caught Throwable and tried to do inline cleanup. In case of OOM errors, such inline-cleanups can result into hung jvms. With this fix, the TaskTracker provides a api to report fatal errors (any throwable other than FSErrror and Exceptions). On catching a Throwable, Mapper/Reducer tries to inform the TT.
+The tasktracker's startup code was modified to use deprecated memory management configuration variables, when specified, and enable memory monitoring of tasks.

+* [MAPREDUCE-818](https://issues.apache.org/jira/browse/MAPREDUCE-818) | *Minor* | **org.apache.hadoop.mapreduce.Counters.getGroup returns null if the group name doesnt exist.**
 
-Fixed a bug in Pipes combiner to reset the spilled bytes count after the spill.
+Fixed a bug in the new org.apache.hadoop.mapreduce.Counters.getGroup() method to return an empty group if group name doesn't exist, instead of null, thus making sure that it is in sync with the Javadoc.

+* [MAPREDUCE-807](https://issues.apache.org/jira/browse/MAPREDUCE-807) | *Blocker* | **Stray user files in mapred.system.dir with permissions other than 777 can prevent the jobtracker from starting up.**
 
-When a job is initialized, it localizes the job conf to the logs dir. Without this patch I never gets deleted. Now when the job retires, the conf is deleted. This local copy is required to display on the webui.
+The JobTracker tries to delete the mapred.system.dir when it is starting up (with the job recovery disabled). The fix provided by this jira is that JobTracker will fail (bail out) with AccessControlException if it fails to delete files/directories in mapred.system.dir due to access control issues.

+* [HADOOP-6213](https://issues.apache.org/jira/browse/HADOOP-6213) | *Blocker* | **Remove commons dependency on commons-cli2**
 
-This patch adds the mapid and reduceid in the http header of mapoutput when being sent to reduce node. Also validates compressed length, decompressed length, mapid and reduceid from http header at reduce node.
+GenericOptionsParser in branch 0.20 depends on commons-cli2. This jira removes the dependency of branch 0.20 on commons-cli2 completely. The problem is seen after 'ant binary' where all the library files are copied to '$hadoop-home/lib' which already has commons-cli2.

-KeyFieldBasedPartitioner throws ArrayOutOfIndex when passed an empty key. This patch hashes empty key to 0 hashcode.
+Various code paths in the framework caught Throwable and tried to do inline cleanup. In case of OOM errors, such inline-cleanups can result into hung jvms. With this fix, the TaskTracker provides a api to report fatal errors (any throwable other than FSErrror and Exceptions). On catching a Throwable, Mapper/Reducer tries to inform the TT.

-* [HADOOP-6949](https://issues.apache.org/jira/browse/HADOOP-6949) | *Major* | **Reduces RPC packet size for primitive arrays, especially long[], which is used at block reporting**
+* [HDFS-708](https://issues.apache.org/jira/browse/HDFS-708) | *Major* | **A stress-test tool for HDFS.**
 
-Increments the RPC protocol version in org.apache.hadoop.ipc.Server from 4 to 5.
-Introduces ArrayPrimitiveWritable for a much more efficient wire format to transmit arrays of primitives over RPC. ObjectWritable uses the new writable for array of primitives for RPC and continues to use existing format for on-disk data.
+Does not currently provide anything but uniform distribution.
+Uses some older depreciated class interfaces (for mapper and reducer)
+This was tested on 0.20 and 0.22 (locally) so it should be fairly backwards compatible.

-* [HADOOP-6730](https://issues.apache.org/jira/browse/HADOOP-6730) | *Major* | **Bug in FileContext#copy and provide base class for FileContext tests**
+* [MAPREDUCE-572](https://issues.apache.org/jira/browse/MAPREDUCE-572) | *Minor* | **If #link is missing from uri format of -cacheArchive then streaming does not throw error.**
 
-**WARNING: No release note provided for this incompatible change.**
+Improved streaming job failure when #link is missing from uri format of -cacheArchive. Earlier it used to fail when launching individual tasks, now it fails during job submission itself.

+* [HADOOP-6949](https://issues.apache.org/jira/browse/HADOOP-6949) | *Major* | **Reduces RPC packet size for primitive arrays, especially long[], which is used at block reporting**
 
-new config: 
-hadoop.security.service.user.name.key
-this setting points to the server principal for RefreshUserToGroupMappingsProtocol.
-The value should be either NN or JT principal depending if it is used in DFAdmin or MRAdmin. The value is set by the application. No need for default value.
+Increments the RPC protocol version in org.apache.hadoop.ipc.Server from 4 to 5.
+Introduces ArrayPrimitiveWritable for a much more efficient wire format to transmit arrays of primitives over RPC. ObjectWritable uses the new writable for array of primitives for RPC and continues to use existing format for on-disk data.

+* [MAPREDUCE-279](https://issues.apache.org/jira/browse/MAPREDUCE-279) | *Major* | **Map-Reduce 2.0**
 
+MapReduce has undergone a complete re-haul in hadoop-0.23 and we now have, what we call, MapReduce 2.0 (MRv2).
 
----
+The fundamental idea of MRv2 is to split up the two major functionalities of the JobTracker, resource management and job scheduling/monitoring, into separate daemons. The idea is to have a global ResourceManager (RM) and per-application ApplicationMaster (AM).  An application is either a single job in the classical sense of Map-Reduce jobs or a DAG of jobs. The ResourceManager and per-node slave, the NodeManager (NM), form the data-computation framework. The ResourceManager is the ultimate authority that arbitrates resources among all the applications in the system. The per-application ApplicationMaster is, in effect, a framework specific library and is tasked with negotiating resources from the ResourceManager and working with the NodeManager(s) to execute and monitor the tasks.
 
-* [MAPREDUCE-2554](https://issues.apache.org/jira/browse/MAPREDUCE-2554) | *Major* | **Gridmix distributed cache emulation system tests.**
+The ResourceManager has two main components:
+\* Scheduler (S)
+\* ApplicationsManager (ASM)
 
-Adds distributed cache related system tests to Gridmix.
+The Scheduler is responsible for allocating resources to the various running applications subject to familiar constraints of capacities, queues etc. The Scheduler is pure scheduler in the sense that it performs no monitoring or tracking of status for the application. Also, it offers no guarantees on restarting failed tasks either due to application failure or hardware failures. The Scheduler performs its scheduling function based the resource requirements of the applications; it does so based on the abstract notion of a Resource Container which incorporates elements such as memory, cpu, disk, network etc.
 
+The Scheduler has a pluggable policy plug-in, which is responsible for partitioning the cluster resources among the various queues, applications etc. The current Map-Reduce schedulers such as the CapacityScheduler and the FairScheduler would be some examples of the plug-in.
 
----
+The CapacityScheduler supports hierarchical queues to allow for more predictable sharing of cluster resources.
+The ApplicationsManager is responsible for accepting job-submissions, negotiating the first container for executing the application specific ApplicationMaster and provides the service for restarting the ApplicationMaster container on failure.
 
-* [MAPREDUCE-2544](https://issues.apache.org/jira/browse/MAPREDUCE-2544) | *Major* | **Gridmix compression emulation system tests.**
+The NodeManager is the per-machine framework agent who is responsible for launching the applications' containers, monitoring their resource usage (cpu, memory, disk, network) and reporting the same to the Scheduler.
 
-Adds system tests for testing the compression emulation feature of Gridmix.
+The per-application ApplicationMaster has the responsibility of negotiating appropriate resource containers from the Scheduler, tracking their status and monitoring for progress.

+* [HDFS-1620](https://issues.apache.org/jira/browse/HDFS-1620) | *Minor* | **Rename HdfsConstants -\> HdfsServerConstants, FSConstants -\> HdfsConstants**
 
-Added config option mapreduce.tasktracker.cache.local.keep.pct to the TaskTracker.  It is the target percentage of the local distributed cache that should be kept in between garbage collection runs.  In practice it will delete unused distributed cache entries in LRU order until the size of the cache is less than mapreduce.tasktracker.cache.local.keep.pct of the maximum cache size.  This is a floating point value between 0.0 and 1.0.  The default is 0.95.

-Emulates the MapReduce compression feature in Gridmix. By default, compression emulation is turned on. Compression emulation can be disabled by setting 'gridmix.compression-emulation.enable' to 'false'.  Use 'gridmix.compression-emulation.map-input.decompression-ratio', 'gridmix.compression-emulation.map-output.compression-ratio' and 'gridmix.compression-emulation.reduce-output.compression-ratio' to configure the compression ratios at map input, map output and reduce output side respectively. Currently, compression ratios in the range [0.07, 0.68] are supported. Gridmix auto detects whether map-input, map output and reduce output should emulate compression based on original job's compression related configuration parameters.

-
-Capture intermediate task resource consumption information:
-\* Time taken so far
-\* CPU load [either at the time the data are taken, or exponentially smoothed]
-\* Memory load [also either at the time the data are taken, or exponentially smoothed]
+* [MAPREDUCE-3157](https://issues.apache.org/jira/browse/MAPREDUCE-3157) | *Major* | **Rumen TraceBuilder is skipping analyzing 0.20 history files**
 
-This would be taken at intervals that depend on the task progress plateaus. For example, reducers have three progress ranges - [0-1/3], (1/3-2/3], and (2/3-3/3] - where fundamentally different activities happen. Mappers have different boundaries that are not symmetrically placed [0-9/10], (9/10-1]. Data capture boundaries should coincide with activity boundaries. For the state information capture [CPU and memory] we should average over the covered interval.

+* [MAPREDUCE-2858](https://issues.apache.org/jira/browse/MAPREDUCE-2858) | *Blocker* | **MRv2 WebApp Security**
+
+A new server has been added to yarn.  It is a web proxy that sits in front of the AM web UI.  The server is controlled by the yarn.web-proxy.address config.  If that config is set, and it points to an address that is different then the RM web interface then a separate proxy server needs to be launched.
+
+This can be done by running
+
+yarn-daemon.sh start proxyserver
 
-**WARNING: No release note provided for this incompatible change.**
+If a separate proxy server is needed other configs also may need to be set, if security is enabled.
+yarn.web-proxy.principal
+yarn.web-proxy.keytab
+
+The proxy server is stateless and should be able to support a VIP or other load balancing sitting in front of multiple instances of this server.

+* [MAPREDUCE-3205](https://issues.apache.org/jira/browse/MAPREDUCE-3205) | *Blocker* | **MR2 memory limits should be pmem, not vmem**
 
-Added a ''-starts-after' option to Rumen's Folder utility. The time duration specified after the '-starts-after' option is an offset with respect to the submit time of the first job in the input trace. Jobs in the input trace having a submit time (relative to the first job's submit time) lesser than the specified offset will be ignored.
+Resource limits are now expressed and enforced in terms of physical memory, rather than virtual memory. The virtual memory limit is set as a configurable multiple of the physical limit. The NodeManager's memory usage is now configured in units of MB rather than GB.

-Fix a misleading exception message in case the Chained Mappers have mismatch in input/output Key/Value pairs between them.
+A multi-level mkdir is now POSIX compliant.  Instead of creating intermediate directories with the permissions of the parent directory, intermediate directories are created with permission bits of rwxrwxrwx (0777) as modified by the current umask, plus write and search permission for the owner.

-* [MAPREDUCE-279](https://issues.apache.org/jira/browse/MAPREDUCE-279) | *Major* | **Map-Reduce 2.0**
+* [HDFS-2465](https://issues.apache.org/jira/browse/HDFS-2465) | *Major* | **Add HDFS support for fadvise readahead and drop-behind**
 
-MapReduce has undergone a complete re-haul in hadoop-0.23 and we now have, what we call, MapReduce 2.0 (MRv2).
+HDFS now has the ability to use posix\_fadvise and sync\_data\_range syscalls to manage the OS buffer cache. This support is currently considered experimental, and may be enabled by configuring the following keys:
+dfs.datanode.drop.cache.behind.writes - set to true to drop data out of the buffer cache after writing
+dfs.datanode.drop.cache.behind.reads - set to true to drop data out of the buffer cache when performing sequential reads
+dfs.datanode.sync.behind.writes - set to true to trigger dirty page writeback immediately after writing data
+dfs.datanode.readahead.bytes - set to a non-zero value to trigger readahead for sequential reads
 
-The fundamental idea of MRv2 is to split up the two major functionalities of the JobTracker, resource management and job scheduling/monitoring, into separate daemons. The idea is to have a global ResourceManager (RM) and per-application ApplicationMaster (AM).  An application is either a single job in the classical sense of Map-Reduce jobs or a DAG of jobs. The ResourceManager and per-node slave, the NodeManager (NM), form the data-computation framework. The ResourceManager is the ultimate authority that arbitrates resources among all the applications in the system. The per-application ApplicationMaster is, in effect, a framework specific library and is tasked with negotiating resources from the ResourceManager and working with the NodeManager(s) to execute and monitor the tasks.
 
-The ResourceManager has two main components:
-\* Scheduler (S)
-\* ApplicationsManager (ASM)
+---
 
-The Scheduler is responsible for allocating resources to the various running applications subject to familiar constraints of capacities, queues etc. The Scheduler is pure scheduler in the sense that it performs no monitoring or tracking of status for the application. Also, it offers no guarantees on restarting failed tasks either due to application failure or hardware failures. The Scheduler performs its scheduling function based the resource requirements of the applications; it does so based on the abstract notion of a Resource Container which incorporates elements such as memory, cpu, disk, network etc. 
+* [MAPREDUCE-3241](https://issues.apache.org/jira/browse/MAPREDUCE-3241) | *Major* | **(Rumen)TraceBuilder throws IllegalArgumentException**
 
-The Scheduler has a pluggable policy plug-in, which is responsible for partitioning the cluster resources among the various queues, applications etc. The current Map-Reduce schedulers such as the CapacityScheduler and the FairScheduler would be some examples of the plug-in.
+Rumen is fixed to ignore the AMRestartedEvent.
 
-The CapacityScheduler supports hierarchical queues to allow for more predictable sharing of cluster resources.
-The ApplicationsManager is responsible for accepting job-submissions, negotiating the first container for executing the application specific ApplicationMaster and provides the service for restarting the ApplicationMaster container on failure.
 
-The NodeManager is the per-machine framework agent who is responsible for launching the applications' containers, monitoring their resource usage (cpu, memory, disk, network) and reporting the same to the Scheduler.
+---
 
-The per-application ApplicationMaster has the responsibility of negotiating appropriate resource containers from the Scheduler, tracking their status and monitoring for progress.
+* [MAPREDUCE-3317](https://issues.apache.org/jira/browse/MAPREDUCE-3317) | *Major* | **Rumen TraceBuilder is emiting null as hostname**
+
+Fixes Rumen to get correct hostName that includes rackName in attempt info.

+* [HDFS-2246](https://issues.apache.org/jira/browse/HDFS-2246) | *Major* | **Shortcut a local client reads to a Datanodes files directly**
 
-Modified application limits to include queue max-capacities besides the usual user limits.
+1. New configurations
+a. dfs.block.local-path-access.user is the key in datanode configuration to specify the user allowed to do short circuit read.
+b. dfs.client.read.shortcircuit is the key to enable short circuit read at the client side configuration.
+c. dfs.client.read.shortcircuit.skip.checksum is the key to bypass checksum check at the client side.
+2. By default none of the above are enabled and short circuit read will not kick in.
+3. If security is on, the feature can be used only for user that has kerberos credentials at the client, therefore map reduce tasks cannot benefit from it in general.
