[jira] [Created] (MAPREDUCE-3670) TaskAttemptListener should respond with errors to unregistered tasks

TaskAttemptListener should respond with errors to unregistered tasks
--------------------------------------------------------------------

                 Key: MAPREDUCE-3670
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3670
             Project: Hadoop Map/Reduce
          Issue Type: Task
          Components: mr-am, mrv2
    Affects Versions: 0.23.0
            Reporter: Siddharth Seth


The TaskAttemptListener currently accepts TaskUmbilical calls from tasks which may have already been unregistered and processes updates. It should just send back Exceptions so that the tasks die.
This isn't critical though - since the task/container would eventually be killed by the AM (via a call to NM stopContainer).
