Hu Ziqian reassigned YARN-8743: ------------------------------- Assignee: Hu Ziqian > capacity scheduler doesn't set node label to reserved container > --------------------------------------------------------------- > > Key: YARN-8743 > URL: https://issues.apache.org/jira/browse/YARN-8743 > Project: Hadoop YARN > Issue Type: Bug > Components: capacity scheduler, scheduler preemption > Reporter: Hu Ziqian > Assignee: Hu Ziqian > Priority: Major > > capacity scheduler doesn't set node label when new a reserved container's > RMContainerImpl. When allocate this container, leafQueue will treat it as a > ignorePartitionExclusivityRMContainer. > It will cause preempt failure. When preempt happens, the preemption policy > will try to preempt the reserved container while leafQueue doesn't remove it > from ignorePartitionExclusivityRMContainers. In our cluster, we found that > preemption policy will always try to preempt the reserved container and > actually preempt nothing. > We set the node label information to reserved container's RMContainerImpl > and redo our test. The preemption performs as expected. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
