      Description

      I configure queue A, B to have 1%, 99% capacity respectively. There is no max capacity for each queue. Set high user limit factor.
      Submit app 1 to queue A. AM container takes 50% of cluster memory. Task containers take another 50%. Submit app 2 to queue B. Preempt task containers of app 1 out. Turns out capacity of queue B increases to 99% but queue A has 5000% used.
