> 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.
