    Description

      A job can succeed before a TaskAttempt's internal state changes to a final state, or before a container transitions to it's final state.
      The AM should wait for TAs and Containers to transition - so that cleanup happens correctly.
      A partial implementation of this handler is already in place. Needs to be finished.
