Vinod Kumar Vavilapalli commented on YARN-2056:

Not sure what this really means.

Preemption today only works across queues and moves around resources across 
queues per demand and usage. Once we have user-level preemption within a queue, 
we can imagine adding the ability to control cross-user preemption, but right 
now this doesn't have any meaning.
