[MAPREDUCE-1481] Streaming should swallow IOExceptions when closing clientOut

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved

Description

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.
