Vitaly updated MAPREDUCE-1481:
------------------------------
Attachment: PipeMapRed.java.patch
This is patch to resolve the issue with IOException. I've moved block
"clientOut_.flush() clientOut_.close()" to separate block with "try catch".
> Streaming should swallow IOExceptions when closing clientOut
> ------------------------------------------------------------
>
> Key: MAPREDUCE-1481
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-1481
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: contrib/streaming
> Affects Versions: 0.20.1, 0.21.0, 0.22.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Attachments: PipeMapRed.java.patch, TestStreamingDontConsumeInput.java
>
>
> in PipeMapRed.mapRedFinished, streaming flushes and closes clientOut_, the
> handle to the subprocess's stdin. If the subprocess has already exited or
> closed its stdin, this will generate a Broken Pipe IOException. This causes
> us to skip waitOutputThreads, which is incorrect, since the subprocess may
> have data still written from stdout that needs to be read.
