Eric Payne commented on YARN-2009:
----------------------------------
[~leftnoteasy], I am confused by your above example:
{quote}
Queue's user-limit-percent = 33
Queue's used=guaranteed=max=12.
There're 3 users (A,B,C) in the queue, order of applications are A/B/C
...
So the computed user-limit-resource will be 6.
...
The actual user-ideal-assignment when doing scheduling is 6/6/0 !
{quote}
If {{minimum-user-limit-percent == 33}}, why is the {{user-limit-resource ==
6}}?
Shouldn't {idealAssigned}} be 4/4/4? not 6/6/0?

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