                 Key: MAPREDUCE-4128
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4128
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 3.0.0
            Reporter: Bikas Saha
            Assignee: Bikas Saha
             Fix For: 3.0.0


The AM seems to assume that all attempts of a completed task (from a previous AM incarnation) would also be completed. There is at least one case in which this does not hold. Case being cancellation of a completed task resulting in a new running attempt.
