Doug Cutting	0caa6bc1b1 More fixes to get working directory to work on Windows. Long-term we should stop using java.io.File for our abstract file paths. On Windows, 'new File(/foo/bar).isAbsolute()' returns false, which caused lots of problems. So I have added a FileSystem.isAbsolute() method that we use internally. I also added a few more .getAbsoluteFile() calls to convert paths into absolute paths so that LocalFileSystem works correctly. Finally I took advantage of file status information cached in DFSFile, eliminating some namenode RPCs.	19 年之前

Doug Cutting	d98cef1ab3 Fix HADOOP-100. Be more consistent about synchronization of access to taskTracker collection. Contributed by Owen O'Malley.	19 年之前
Doug Cutting	03c953c0dc Fix for HADOOP-107. As they were written, dfs blocks were both trickled to a datanode and tee'd to a temp file (in case the connection to the datanode failed). Now they're only written to the temp file, with no connection to the datanode made until the block is complete. This reduces the number of long-lived mostly-idle connections to datanodes, which was causing problems. It also simplifies the DFSClient code significantly.	19 年之前
Doug Cutting	294aa869c5 Fix for HADOOP-103, part II: I forgot to add this file the first time!	19 年之前
Doug Cutting	eeea2a252d Fix for HADOOP-103. Add a base class for Mapper and Reducer implementations that implements Closeable and JobConfigurable. Use it in supplied Mappers & Reducers. Also some minor improvements to demos. Contributed by Owen O'Malley.	19 年之前
Doug Cutting	7d0429d4d2 Fix for HADOOP-110. Reuse keys and values when mapping. Contributed by Owen O'Malley.	19 年之前
Doug Cutting	ec87d7e0e3 Fix for HADOOP-2. The combiner now clones keys and values, so mappers may now safely reuse emitted keys and values. Contributed by Owen O'Malley.	19 年之前
Doug Cutting	ecf45fd810 Fix for HADOOP-112. All operations on local files are now performed	19 年之前
Doug Cutting	7018745fac Fix for HADOOP-84. Improve error and log messages when block cannot be obtained by including file name and offset. Also removed a few unused variables. Contributed by Konstantin Shvachko.	19 年之前
Doug Cutting	95091af3ce Fix HADOOP-33. Avoid calling df too frequently by caching values internally. Contributed by Konstantin Shvachko.	19 年之前
Doug Cutting	4eccd587cc Fix HADOOP-67. Add a public API for dfs statistics. Also switch to use the public API for reporting in DFSShell.	19 年之前
Andrzej Bialecki	2948bf60de Add a tool for checking DFS consistency (HADOOP-101).	19 年之前
Doug Cutting	9f4fa16216 Fix for file names with spaces.	19 年之前
Doug Cutting	27a97ef6d3 Always return an absolute pathname for local files. This fixes	19 年之前
Doug Cutting	24465c6af4 Fix unit tests on Windows. Don't assume that, just because a pathname begins with a slash that it also returns true for File.isAbsolute(). Instead use getAbsoluteFile() to force such things to be absolute.	19 年之前
Doug Cutting	943ba3132a Document the new format command.	19 年之前
Doug Cutting	73be419f00 Fix for HADOOP-19. A namenode must now be formatted before it may be used. Attempts to start a namenode in an unformatted directory will fail, rather than automatically creating a new, empty filesystem, causing existing datanodes to delete all blocks. Thus a mis-configured dfs.data.dir should no longer cause data loss.	19 年之前
Doug Cutting	82236adb3c Move checking of output directory existence from JobClient to OutputFormat, so that it can be overridden. Add a base class for OutputFormat that implements this new method.	19 年之前
