----------------------------------
[~kasha], do you have any concern if using
{{SchedulerApplicationAttempt.getAppAttemptResourceUsage().getPending()}}.
> FairScheduler: Apps that have no resource demand should not participate

> At present, all of the 'running' apps participate the scheduling process,
> however, most of them may have no resource demand on a production cluster, as
> the app's status is running other than waiting for resource at the most of
> the app's lifetime. It's not a wise way we sort all the 'running' apps and
> try to fulfill them, especially on a large-scale cluster which has heavy
> scheduling load.
