[jira] [Created] (MAPREDUCE-5570) Map task attempt with fetch failure has incorrect attempt finish time

Jason Lowe created MAPREDUCE-5570:
-------------------------------------

             Summary: Map task attempt with fetch failure has incorrect attempt finish time
                 Key: MAPREDUCE-5570
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5570
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mr-am, mrv2
    Affects Versions: 2.1.1-beta, 0.23.9
            Reporter: Jason Lowe


If a map task attempt is retroactively failed due to excessive fetch failures reported by reducers then the attempt's finish time is set to the time the task was retroactively failed rather than when the task attempt completed.  This causes the map task attempt to appear to have run for much longer than it actually did.
