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

             Summary: NMs reconnecting with changed capabilities can lead to wrong cluster resource calculations on fair scheduler
                 Key: YARN-4761
                 URL: https://issues.apache.org/jira/browse/YARN-4761
             Project: Hadoop YARN
          Issue Type: Bug
          Components: fairscheduler
    Affects Versions: 2.6.4
            Reporter: Sangjin Lee
            Assignee: Sangjin Lee


YARN-3802 uncovered an issue with the scheduler where the resource calculation can be incorrect due to async event handling. It was subsequently fixed by YARN-4344, but it was never fixed for the fair scheduler.
