> If RM HA is enabled and used Zookeeper store for RM State Store.
> If for any reason Any app gets rejected and directly goes to NEW to FAILED
> then final transition makes that to RMApps and Completed Apps memory structure but that
doesn't make it to State store.
> Now when RMApps default limit reaches it starts deleting apps from memory and store.
In that case it try to delete this app from store and fails which causes RM to crash.
> Thanks,
> Mayank
