>                 URL: https://issues.apache.org/jira/browse/YARN-11066
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: capacityscheduler, yarn
>    Affects Versions: 3.4.0
>            Reporter: Tamas Domok
>            Assignee: Tamas Domok
>            Priority: Critical

> Reproduction steps:
> 1. Use the attached configuration: [^capacity-scheduler.xml]
> 2. Enable *yarn.acl.enable* in yarn-site.xml.
> 3. Try to submit an application with any user other than *user1, user2, user3*.
> {code}
> yarn jar hadoop-mapreduce-examples-3.4.0-SNAPSHOT.jar pi 1 10
> {code}
> The *first* app submission will succeed with *someuser:somegroup* the *root.parent.somegroup.someuser* queue will be created. When the *root.parent.somegroup* dynamic parent queue already exists then the ACLs in *root.parent* will be checked and the *someuser* won't be able to submit an another app. But queues are deleted automatically, so this is a serious security issue.
> This issue doesn't happen when dynamic parent queue is not created just a dynamic leaf queue.
> Another inconsistency is that the ACLs configured with templates works on dynamic leaf queues, but not when there is a dynamic parent queue too.
