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..)
