bufferSize argument is ignored in FileSystem.create(File, boolean, int)
-----------------------------------------------------------------------
Key: HADOOP-40
URL: http://issues.apache.org/jira/browse/HADOOP-40
Project: Hadoop
Type: Bug
Components: fs
Reporter: Konstantin Shvachko
Priority: Minor
org.apache.hadoop.fs.FileSystem.create(File f, boolean overwrite, int
bufferSize)
ignores the input parameter bufferSize.
It passes further down the internal configuration, which includes the buffer
size, but not the parameter value.
This works fine within the file system, since everything that calls create
extracts buffer size from the same config.
MapReduce although is probably affected by that, see
org.apache.hadoop.io.SequenceFile.Sorter.MergeQueue.MergeQueue(int size, String
outName, boolean done)
The attached patch would fix it.
