Subject [jira] [Commented] (YARN-6380) FSAppAttempt keeps redundant copy of the queue
Date Fri, 24 Mar 2017 23:21:41 GMT

Yufei Gu commented on YARN-6380:
--------------------------------

Redundancy is evil. Thanks for fixing this. Would you mind fixing the casting in getHeadRoom()
since we are here?
{code}
  public Resource getHeadroom() {
    final FSQueue queue = (FSQueue) this.queue;
{code}

> 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}}.
