Summary: Improve Locality Scheduling when cluster is busy Key: YARN-9671 URL: https://issues.apache.org/jira/browse/YARN-9671 Project: Hadoop YARN Issue Type: Improvement Reporter: Muhammad Samir Khan Assignee: Muhammad Samir Khan When a cluster is very busy, scheduling opportunities are few and far between. Scheduling opportunities are how an application knows when to give up looking for decent locality. It doesn't make sense to work hard waiting for locality when the odds of it coming are very small and it may actually take a very long time to actually give up. This causes the priority of queues to be violated which is the last thing we want to do when the cluster is full. * Add metrics for queue priority inversions. * Add mode to disable skipping locality when cluster is busy. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
