Jian He commented on YARN-1493:
-------------------------------
bq. The information about submission to various queues is lost? It is not
needed?
Investigated that the queue passed in the earlier code is only used in
ParentQueue.submitApplication for comparing the queue's name with the
parentQueue's name for validation. None of the test is using this requirement.
And Also, for every single test, the test is using the same queue.
> Schedulers don't recognize apps separately from app-attempts

> Today, scheduler is tied to attempt only.
> We need to separate app-level handling logic in scheduler. We can add new
> app-level events to the scheduler and separate the app-level logic out. This
> is good for work-preserving AM restart, RM restart, and also needed for
> differentiating app-level metrics and attempt-level metrics.
