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.
