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.
