Jason Lowe created MAPREDUCE-5891:
-------------------------------------

             Summary: Improved shuffle error handling across NM restarts
                 Key: MAPREDUCE-5891
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5891
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
    Affects Versions: 2.5.0
            Reporter: Jason Lowe


To minimize the number of map fetch failures reported by reducers across an NM restart it would be nice if reducers only reported a fetch failure after trying for at specified period of time to retrieve the data.
