Varun Saxena reassigned YARN-3489:
----------------------------------
Assignee: Varun Saxena
> RMServerUtils.validateResourceRequests should only obtain queue info once
> -------------------------------------------------------------------------
>
> Key: YARN-3489
> URL: https://issues.apache.org/jira/browse/YARN-3489
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager
> Affects Versions: 2.6.0
> Reporter: Jason Lowe
> Assignee: Varun Saxena
>
> Since the label support was added we now get the queue info for each request
> being validated in SchedulerUtils.validateResourceRequest. If
> validateResourceRequests needs to validate a lot of requests at a time (e.g.:
> large cluster with lots of varied locality in the requests) then it will get
> the queue info for each request. Since we build the queue info this
> generates a lot of unnecessary garbage, as the queue isn't changing between
> requests. We should grab the queue info once and pass it down rather than
> building it again for each request.
