> Key: YARN-3894
> URL: https://issues.apache.org/jira/browse/YARN-3894
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler
> Reporter: Bibin A Chundatt
> Assignee: Bibin A Chundatt
> Priority: Critical
> Attachments: 0001-YARN-3894.patch, 0002-YARN-3894.patch,
> capacity-scheduler.xml
>
>
> 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 =
> parseQueue(this, conf, null, CapacitySchedulerConfiguration.ROOT,
> queues, queues, noop);
> 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*
