[jira] [Created] (YARN-6952) Enable scheduling monitor in FS

Yufei Gu created YARN-6952:
------------------------------

             Summary: Enable scheduling monitor in FS
                 Key: YARN-6952
                 URL: https://issues.apache.org/jira/browse/YARN-6952
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: fairscheduler, resourcemanager
            Reporter: Yufei Gu
            Assignee: Yufei Gu


{{SchedulingEditPolicy#init}} doesn't need to take interface {{PreemptableResourceScheduler}} as the scheduler input. A ResourceScheduler is good enough. With that change, fair scheduler is able to use scheduling monitor(e.g. invariant checks) as CS does. Further more, there is no need for interface {{PreemptableResourceScheduler}}.
