> 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

>
> 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.
