> *PROBLEM*
> How to enable preemption on a single queue in a cluster?
> *DESCRIPTION*
> As of today the only way to enable preemption at a queue level is:
> * Enable cluster level preemption
> * Disable preemption on the queues where not required using yarn.scheduler.capacity.<queue-path>.disable_preemption to true
> Can we have some sort of a parameter like 
> *_yarn.scheduler.capacity.<queue-path>.enable_preemption_*
> which would just enable preemption per queue instead of going the other way round which is more time consuming and error prone.
