Assignee: (was: Bilwa S T)
> NodeListManager event improvement
> ---------------------------------
>
> Key: YARN-9618
> URL: https://issues.apache.org/jira/browse/YARN-9618
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Bibin Chundatt
> Priority: Critical
>
> Current implementation nodelistmanager event blocks async dispacher and can
> cause RM crash and slowing down event processing.
> # Cluster restart with 1K running apps . Each usable event will create 1K
> events over all events could be 5k*1k events for 5K cluster
> # Event processing is blocked till new events are added to queue.
> Solution :
> # Add another async Event handler similar to scheduler.
> # Instead of adding events to dispatcher directly call RMApp event handler.
