Subject [jira] Created: (MAPREDUCE-2374) Should not use PrintWriter to write taskjvm.sh
Date Wed, 09 Mar 2011 22:04:59 GMT
Should not use PrintWriter to write taskjvm.sh
----------------------------------------------

                 Key: MAPREDUCE-2374
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2374
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
             Fix For: 0.22.0


Our use of PrintWriter in TaskController.writeCommand is unsafe, since that class swallows
all IO exceptions. We're not currently checking for errors, which I'm seeing result in occasional
task failures with the message "Text file busy" - assumedly because the close() call is failing
silently for some reason.
