-----------------------------------------------------------
The RM will never provide the final DAG status as it only knows about yarn apps
and not Tez dags. A YARN app can run multiple DAGs. The best that YARN can
provide is info that whether a DAG is completed or not based on whether the
YARN app has completed or not.

> Tez UI: DAG status is not correct when application history is not accessible.
