Doug Cutting updated HADOOP-40:
-------------------------------

    Attachment:     (was: bufferSize.patch)

> 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
>  Attachments: BufferSize.patch
>
> 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.
