Wanqiang Ji created YARN-9041: --------------------------------- Summary: Optimize FSPreemptionThread#identifyContainersToPreempt method Key: YARN-9041 URL: https://issues.apache.org/jira/browse/YARN-9041 Project: Hadoop YARN Issue Type: Improvement Reporter: Wanqiang Ji Assignee: Wanqiang Ji
In FSPreemptionThread#identifyContainersToPreempt method, I suggest if AM preemption, and locality relaxation is allowed, then the search space is expanded to all nodes changed to the remaining nodes. The remaining nodes are equal to all nodes minus the potential nodes. Judging condition changed to: # rr.getRelaxLocality() # !ResourceRequest.isAnyLocation(rr.getResourceName()) # bestContainers != null # bestContainers.numAMContainers > 0 If I understand the deviation, please criticize me. thx~ -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-dev-h...@hadoop.apache.org
