Wangda Tan commented on YARN-6451: ---------------------------------- Thanks [~curino]/[~chris.douglas], Beyond metrics, i think there're many information are not inside metrics, such as order of container allocation to ensure FIFO/fairness, etc. Have you thought about how to formalize these requirements? > Add RM monitor validating metrics invariants > -------------------------------------------- > > Key: YARN-6451 > URL: https://issues.apache.org/jira/browse/YARN-6451 > Project: Hadoop YARN > Issue Type: New Feature > Reporter: Carlo Curino > Assignee: Carlo Curino > Fix For: 3.0.0-alpha3 > > Attachments: YARN-6451.v0.patch, YARN-6451.v1.patch, > YARN-6451.v2.patch, YARN-6451.v3.patch, YARN-6451.v4.patch, YARN-6451.v5.patch > > > 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..) -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
