["Bibin A Chundatt (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-3894?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Bibin A Chundatt updated YARN-3894:
-----------------------------------
    Attachment: capacity-scheduler.xml

Attaching conf used for capacity-scheduler.xml . On Serviceinit the queue is not failing but on reinitialize the same is failing. yarn-site added in YARN-3893

> Currently in capacity Scheduler when capacity configuration is wrong
> RM shutdown is the current behaviour, 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 .
