Summary: Fifo and Fair intra-queue preemption goes on indefinitely when apps are in pending state due to max AM limit reached Key: YARN-10617 URL: https://issues.apache.org/jira/browse/YARN-10617 Project: Hadoop YARN Issue Type: Improvement Components: capacity scheduler Affects Versions: 3.1.1 Reporter: VADAGA ANANYO RAO Assignee: VADAGA ANANYO RAO This case occurs when: 1. an application gets submitted in a cluster running at max-AM limit. 2. The new job requests AM resource. So it has 1 pending request. 3. To fulfil this request, the preemption logic preempts 1 resource from a running app. 4. Because the cluster is at max-AM limit, the scheduler re-assigns the preempted container back to the running app. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
