Subject [jira] Created: (MAPREDUCE-1481) Streaming should swallow IOExceptions when closing clientOut
Date Thu, 11 Feb 2010 00:54:28 GMT
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.
