             Summary: LLAP: Better handling of query completion notifications in tez plugins
                 Key: HIVE-13078
                 URL: https://issues.apache.org/jira/browse/HIVE-13078
             Project: Hive
          Issue Type: Improvement
            Reporter: Siddharth Seth


Especially post HIVE-12959 - the various plugins should handle dagCompletion notifications better. Relevant even without that - dag failures for instance.
e.g. drop pending scheduling requests. Avoid sending state change updates. Avoid trying to launch new tasks. Notifications will eventually coming in cancelling all tasks - so it's partially handled.
