>
> The killJob is invokedby
> - grunt kill command
> - thread interrupt in Main (mostly in case of Oozie)
> - HangingJobKiller during shutdown
> killJob tries to kill the DAG again even if it was completed. It closes the
> session but does not remove it from the TezSessionManager session pool.
> Though both of these are minor issues and have no adverse impact (trying to
> kill a done DAG would be ignored by Tez AM and TezSessionManager would later
> check status of the session and remove it from the pool) the fix would avoid
> the two unnecessary calls to AM.
