> the Application Master of Hive on Spark always live on the yarn if the Hive client do not exit(such as one session in HiveServer2), which will accupy lots of resources, we should control the AM shut down when there is no more jobs submit.
> Now Tez use the param  ` tez.session.am.dag.submit.timeout.secs` to control the DAGAppMaster on the yarn to shut down.
> So here Spark need to do this too.
