Daryn Sharp created YARN-6681: --------------------------------- Summary: Eliminate double-copy of child queues in canAssignToThisQueue Key: YARN-6681 URL: https://issues.apache.org/jira/browse/YARN-6681 Project: Hadoop YARN Issue Type: Sub-task Components: resourcemanager Affects Versions: 2.8.0 Reporter: Daryn Sharp Assignee: Daryn Sharp
20% of the time in {{AbstractCSQueue#canAssignToThisQueue}} is spent performing two duplications a treemap of child queues into a list - once to test for null, second to see if it's empty. Eliminating the dups reduces the overhead to 2%. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
