>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: capacityscheduler
>            Reporter: Bibin A Chundatt
>            Assignee: Bibin A Chundatt
>            Priority: Critical

> Currently in capacity Scheduler when capacity configuration is wrong
> RM will shutdown, but not incase of NodeLabels capacity mismatch
> In {{CapacityScheduler#initializeQueues}}
> {code}
>   private void initializeQueues(CapacitySchedulerConfiguration conf)
>     throws IOException {   
>     root = 
>         parseQueue(this, conf, null, CapacitySchedulerConfiguration.ROOT, 
>             queues, queues, noop);
>     labelManager.reinitializeQueueLabels(getQueueToLabels());
>     root =

>     LOG.info("Initialized root queue " + root);
>     initializeQueueMappings();
>     setQueueAcls(authorizer, queues);
>   }
> {code}
> {{labelManager}} is initialized from queues and calculation for Label level capacity
mismatch happens in {{parseQueue}} . So during initialization {{parseQueue}} the labels will
be empty . 
> *Steps to reproduce*
> # Configure RM with capacity scheduler
> # Add one or two node label from rmadmin
> # Configure capacity xml with nodelabel but issue with capacity configuration for already
added label
> # Restart both RM
> # Check on service init of capacity scheduler node label list is populated 
> *Expected*
> RM should not start 
> *Current exception on reintialize check*
