> 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.
