Yufei Gu created YARN-7207: ------------------------------ Summary: Cache the local host name when getting application list in RM Key: YARN-7207 URL: https://issues.apache.org/jira/browse/YARN-7207 Project: Hadoop YARN Issue Type: Improvement Components: RM Affects Versions: 3.1.0 Reporter: Yufei Gu Assignee: Yufei Gu
{{getLocalHostName()}} is invoked for generating the report for each application, which means it is called 1000 times for each {{getApplications()}} if there are 1000 apps in RM. Some user got a performance issue when {{getLocalHostName()}} is slow under some network envs. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
