Key: YARN-10702
URL: https://issues.apache.org/jira/browse/YARN-10702
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Affects Versions: 2.10.1, 3.4.0
Reporter: Jim Brennan
Assignee: Jim Brennan
Add a cluster metric to track the cpu usage of the ResourceManager Event
Processing thread. This lets us know when the critical path of the RM is
running out of headroom.
This feature was originally added for us internally by [~nroberts] and we've
been running with it on production clusters for nearly four years.
