Reduce task should stop shuffle-retrying in case of out-of-memory errors
------------------------------------------------------------------------

                 Key: HADOOP-5270
                 URL: https://issues.apache.org/jira/browse/HADOOP-5270
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Amareshwari Sriramadasu
             Fix For: 0.21.0


In ReduceTask, MapOutputCopier threads catch Throwble and retry happens for the shuffle. It
should not retry incase of Errors suchas OutOfMemoryError etc.

May be it should retry only in case of Connect/Read failures and die in all other cases. Thoughts?
