             Summary: FairScheduler: Collect metrics on duration of critical 
methods that affect performance
                 Key: YARN-2352
                 URL: https://issues.apache.org/jira/browse/YARN-2352
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: scheduler
    Affects Versions: 2.4.1
            Reporter: Karthik Kambatla
            Assignee: Karthik Kambatla


We need more metrics for better visibility into FairScheduler performance. At 
the least, we need to do this for (1) handle node events, (2) update, (3) 
compute fairshares, (4) preemption.
