Daniel Templeton updated YARN-6380:

Per an offline conversation with [~kasha], here's an updated patch that uses the {{getQueue()}}
method instead.

> 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}}.
