             Summary: Tracking of completed dags is a slow memory leak
                 Key: HIVE-12445
                 URL: https://issues.apache.org/jira/browse/HIVE-12445
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.0.0
            Reporter: Siddharth Seth


LLAP daemons track completed DAGs, but never clean up these structures. This is 
primarily to disallow out of order executions. Evaluate whether that can be 
avoided - otherwise this structure needs to be cleaned up with a delay.
