Subject [jira] [Created] (YARN-6451) Create a monitor to check whether we maintain RM (scheduling) invariants
Date Wed, 05 Apr 2017 21:43:42 GMT
Carlo Curino created YARN-6451:
----------------------------------

             Summary: Create a monitor to check whether we maintain RM (scheduling) invariants
                 Key: YARN-6451
                 URL: https://issues.apache.org/jira/browse/YARN-6451
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Carlo Curino
            Assignee: Carlo Curino


For SLS runs, as well as for live test clusters (and maybe prod), it would be useful to have
a mechanism to continuously check whether core invariants of the RM/Scheduler are respected
(e.g., no priority inversions, fairness mostly respected, certain latencies within expected
range, etc..)
