          Components: contrib/streaming
            Reporter: Tom White
             Fix For: 0.19.0


When debugging streaming programs, it would be useful to have the last few lines from stderr in the exception message (which is shown in the task's status display).

Chris Douglas commented on HADOOP-3789:
---------------------------------------

Just a few nits:
* Instead of {{stderrStatus.delete(0, stderrStatus.length())}}, {{stderrStatus.setLength(0)}} should do the same thing. The former should just make a call to System.arraycopy- which won't do anything- but the latter is a little more readable.
* Instead of appending to the buffer and copying over the excess, stderrStatusLimit might be enforced more strictly by doing the length check and delete before the append of lineStr
* It looks like the buffer size config gets thrown away, instead of being assigned to stderrStatusLimit:

Tom White updated HADOOP-3789:
------------------------------

    Attachment: hadoop-3789.patch

This patch extends PipeMapRed so that when a HadoopStreaming subprocess terminates with a nonzero exit code, and it's recognized as task failure due to stream.non.zero.exit.is.failure, the resulting Java exception carries recent subprocess stderr. "Recent" means more recent than the last "reporter:" line on stderr, limited to a maximum of 2K (configurable)
