>       // 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.
