Weiwei Yang commented on YARN-8511: ----------------------------------- Thanks [~leftnoteasy], [~kkaranasos]! > When AM releases a container, RM removes allocation tags before it is > released by NM > ------------------------------------------------------------------------------------ > > Key: YARN-8511 > URL: https://issues.apache.org/jira/browse/YARN-8511 > Project: Hadoop YARN > Issue Type: Bug > Components: capacity scheduler > Affects Versions: 3.1.0 > Reporter: Weiwei Yang > Assignee: Weiwei Yang > Priority: Major > Fix For: 3.2.0, 3.1.1 > > Attachments: YARN-8511.001.patch, YARN-8511.002.patch, > YARN-8511.003.patch, YARN-8511.004.patch > > > User leverages PC with allocation tags to avoid port conflicts between apps, > we found sometimes they still get port conflicts. This is a similar issue > like YARN-4148. Because RM immediately removes allocation tags once > AM#allocate asks to release a container, however container on NM has some > delay until it actually gets killed and released the port. We should let RM > remove allocation tags AFTER NM confirms the containers are released. -- 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
