Daniel Templeton commented on YARN-6380:
----------------------------------------
It is a pointer to the same queue at creation time, but in
{{FairScheduler.executeMove()}}, line 1662 we set the new queue using the
{{setQueue()}} method, which sets the {{SchedulerApplicationAttempt#queue}} but
not the {{FSAppAttempt#fsQueue}}.
> FSAppAttempt keeps redundant copy of the queue

> URL: https://issues.apache.org/jira/browse/YARN-6380
> Project: Hadoop YARN
> Issue Type: Bug
> Components: fairscheduler
> Affects Versions: 3.0.0-alpha2
> Reporter: Daniel Templeton
> Assignee: Daniel Templeton

>
>
> The {{FSAppAttempt}} class defines its own {{fsQueue}} variable that is a
> second copy of the {{SchedulerApplicationAttempt}}'s {{queue}} variable.
> Aside from being redundant, it's also a bug, because when moving
> applications, we only update the {{SchedulerApplicationAttempt}}'s {{queue}},
> not the {{FSAppAttempt}}'s {{fsQueue}}.
