TaskAttemptListener should respond with errors to unregistered tasks

    Details

    • Type: Task
    • Status: Open

      Description

      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).
