-----------------------------------

             Summary: Fine-grained SchedulerNode synchronization
                 Key: YARN-9805
                 URL: https://issues.apache.org/jira/browse/YARN-9805
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Ahmed Hussein
            Assignee: Ahmed Hussein


Yarn schedulerNode and RMNode are using synchronized methods on reading and updating the resources.

Instead, use read-write reentrant locks to provide fine-grained locking and to avoid blocking concurrent reads.
