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
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.
