> Avoid unnecessary QueueMappingEntity creations
> ----------------------------------------------
>
> Key: YARN-10279
> URL: https://issues.apache.org/jira/browse/YARN-10279
> Project: Hadoop YARN
> Issue Type: Task
> Reporter: Gergely Pollak
> Assignee: Hudáky Márton Gyula
> Priority: Minor
> Attachments: YARN-10279.001.patch, YARN-10279.002.patch
>
>
> In CS UserGroupMappingPlacementRule and AppNameMappingPlacementRule classes
> we create new instances of QueueMappingEntity class. In some cases we simply
> copy the already received class, so we just duplicate it, which is
> unnecessary since the class is immutable.
> This is just a minor improvement, probably doesn't have much impact, but
> still puts some unnecessary load on GC.
