Dominant resource fairness functionality

Hi,

 

I would like to know how DRF scheduling behaves in below scenarios,

 

I have two pools default & Priority. Priority pool has two sub pools Priority-1 $ Priority-2. 

 

Default - 20%

Priority - 80%

      Priority-1 - 30%

      Priority-2 - 50%

 

If in a scenario where there are no jobs running in Priority-2 and other pools are fully occupied. How 50% of the resources from Priority-2 are allocated to other pools. Does all the 50% is alloacted to Priority-1 or shared across default and priority-1?
