VADAGA ANANYO RAO created YARN-10559: ----------------------------------------
Summary: Fair sharing intra-queue preemption support in Capacity Scheduler Key: YARN-10559 URL: https://issues.apache.org/jira/browse/YARN-10559 Project: Hadoop YARN Issue Type: Improvement Components: capacityscheduler Affects Versions: 3.1.4 Reporter: VADAGA ANANYO RAO Fix For: 3.1.4 Attachments: FairOP_preemption-design_doc_v1.pdf Usecase: Due to the way Capacity Scheduler preemption works, If a single user submits a large application to a queue (using 100% of resources), that job will not be preempted by future applications from the same user within the same queue. This implies that the later applications will be forced to wait for completion of the long running application. This prevents multiple long running, large, applications from running concurrently. Support fair sharing among apps while preempting applications from same queue. -- 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
