Add > some local caching to take advantage of this fact. > Will post patch shortly. Patch includes a simple throughput test that > demonstrates when we have users at their user-limit, the number of > NodeUpdateSchedulerEvents we can process can be improved from 13K/sec to > 50K/sec. -- 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
