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
