> {{LeafQueue#updateApplicationPriority}}
> {code}
> getOrderingPolicy().removeSchedulableEntity(attempt);
> // Update new priority in SchedulerApplication
> attempt.setPriority(newAppPriority);
> getOrderingPolicy().addSchedulableEntity(attempt);
> {code}
> We should add again to ordering policy only when attempt available in first
> case.Else during application attempt removal will try to iterate on killed
> application still available in pending Ordering policy.Which can cause RM to
> crash.
