[jira] [Created] (YARN-2920) CapacityScheduler should be notified when labels on nodes changed

Wangda Tan created YARN-2920:
--------------------------------

             Summary: CapacityScheduler should be notified when labels on nodes changed
                 Key: YARN-2920
                 URL: https://issues.apache.org/jira/browse/YARN-2920
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wangda Tan
            Assignee: Wangda Tan


Currently, labels on nodes changes will only be handled by RMNodeLabelsManager, but that is not enough upon labels on nodes changes:
- Scheduler should be able to do take actions to running containers. (Like kill/preempt/do-nothing)
- Used / available capacity in scheduler should be updated for future planning.

We need add a new event to pass such updates to scheduler
