MR AM for sort-job going out of memory
--------------------------------------

                 Key: MAPREDUCE-3333
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3333
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: applicationmaster, mrv2
    Affects Versions: 0.23.0
            Reporter: Vinod Kumar Vavilapalli
            Priority: Blocker


[~Karams] just found this. The usual sort job on a 350 node cluster hung due to OutOfMemory and eventually failed after an hour instead of the usual odd 20 minutes.
