Subject [jira] [Created] (YARN-10390) LeafQueue: retain user limits cache across assignContainers() calls
Date Thu, 06 Aug 2020 21:14:00 GMT
Muhammad Samir Khan created YARN-10390:
------------------------------------------

             Summary: LeafQueue: retain user limits cache across assignContainers() calls
                 Key: YARN-10390
                 URL: https://issues.apache.org/jira/browse/YARN-10390
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: capacity scheduler, capacityscheduler
            Reporter: Muhammad Samir Khan
            Assignee: Muhammad Samir Khan
         Attachments: user limit caching profile.pdf

Currently, user limits are cached locally in leafQueue.assignContainers call to avoid repeating
some steps. This cache can be retained across the calls.

Will put up a PR soon. Profiling was done using the proposed changes in TestCapacitySchedulerPerf.
