[jira] [Created] (YARN-4198) CapacityScheduler locking / synchronization improvements

Carlo Curino created YARN-4198:
----------------------------------

             Summary: CapacityScheduler locking / synchronization improvements
                 Key: YARN-4198
                 URL: https://issues.apache.org/jira/browse/YARN-4198
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Carlo Curino


In the context of YARN-4193 (which stresses the RM/CS performance) we found several performance problems with  in the locking/synchronization of the CapacityScheduler, as well as inconsistencies that do not normally surface (incorrect locking-order of queues protected by CS locks etc). This JIRA proposes several refactoring that improve this.
