                 Key: YARN-3008
                 URL: https://issues.apache.org/jira/browse/YARN-3008

          Issue Type: Improvement
          Components: fairscheduler

Instead of a big monolithic lock on FairScheduler, we can have an explicit lock on queuemanager and revisit all synchronized methods in FairScheduler
