[jira] [Created] (YARN-7844) Expose metrics for scheduler operation (allocate, schedulerEvent) to JMX

Wei Yan created YARN-7844:
-----------------------------

             Summary: Expose metrics for scheduler operation (allocate, schedulerEvent) to JMX
                 Key: YARN-7844
                 URL: https://issues.apache.org/jira/browse/YARN-7844
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: scheduler
            Reporter: Wei Yan
            Assignee: Wei Yan


Currently FairScheduler's FSOpDurations records some scheduler operation metrics: nodeUpdateCall, preemptCall, etc. We may need similar for CapacityScheduler. Also, need to add more metrics there. This could help monitor the RM scheduler performance, and get more insights whether scheduler is under-pressure.
