----------------------------------
Hi [~eepayne],
Really appreciate your help on testing and give feedbacks to this feature from
the beginning. We have exactly same requirement: user share queues with
different app priority. I was not trying to declare this feature is completed
-- I don't think user should use it before we fix the user limit issues you
found.
My suggestion is： commit existing patch, at least it works for single user and
(I think) it doesn't have fundamental issue. We can fix it in the next patch
with highest priority. Does this sound OK to you? I just feel reviewing changes
of this patch is too painful, every time I felt I'm reviewing a new patch
because it's hard to get which place changed :)
I think the next patch should be incremental and much easier to be reviewed.
Please let me know your thoughts, thanks.

> While preempting containers based on the queue ideal assignment, we may need
> to consider preempting the low priority application containers first.
