Hudáky Márton Gyula commented on YARN-10279: -------------------------------------------- This patch is applied on the patch in this jira: https://issues.apache.org/jira/browse/YARN-10281 We will retest it after the other one is merged. > 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 > > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
