[jira] [Commented] (YARN-6165) Intra-queue preemption occurs even
when preemption is turned off for a specific queue.
[ https://issues.apache.org/jira/browse/YARN-6165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15859987#comment-15859987 ]
Eric Payne commented on YARN-6165:
----------------------------------
Use Case:
- Configure queues with cluster-wide preemption on, but a specific queue's preemption off (see above).
- Submit a job at priority 1 that fills the entire queue
- Submit a job as the same user at priority 2
Containers from the first job will be preempted when they shouldn't be.
> Intra-queue preemption occurs even when preemption is turned off for a specific queue.
