      Description

      The ProportionalCapacityPreemptionPolicy preempts as many containers from applications as it can during it's preemption run. For fifo this makes sense, as it is prempting in reverse order & therefore maintaining the primacy of the "oldest". For fair ordering this does not have the desired effect - instead, it should preempt a number of containers from each application which maintains a fair balance /close to a fair balance between them
