Nathan Roberts created YARN-6775: ------------------------------------ Summary: CapacityScheduler: Improvements to assignContainers() Key: YARN-6775 URL: https://issues.apache.org/jira/browse/YARN-6775 Project: Hadoop YARN Issue Type: Sub-task Components: capacityscheduler Affects Versions: 3.0.0-alpha3, 2.8.1 Reporter: Nathan Roberts Assignee: Nathan Roberts
There are several things in assignContainers() that are done multiple times even though the result cannot change (canAssignToUser, canAssignToQueue). 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
