Jeff Zhang updated TEZ-1885:
----------------------------
    Description: 
Here's logs which demonstrate the scenario: Shutdown AM -> submit new DAG
But the error message is not correct (" App master already running a DAG" ), it 
should be "AM unable to accept new DAG submissions, In the process of shutting 
down"
