Siddharth Seth commented on TEZ-2206:
-------------------------------------
DAGImpl needs to be constructed with the current ugi.getName instead of
dagAppMasterUgi.getName. Will have to evaluate the impact of making this change
though.
> DAG user sent to ATS via DAGSubmittedEvent is always the AM user
