Jason Lowe commented on YARN-7813:
----------------------------------
Thanks for the patch!
It looks like this has the potential to be surprising to users who had turned
on in-queue preemption. Previously the intra queue preemption selector was
keying off of cross-queue preemption disable, but now it will key off of a new
property. Will this cause queues to start performing intra-queue preemption
that did not previously with the same configs or vice-versa?
"intreQueuePreemptionDisabled" s/b "intraQueuePreemptionDisabled"
Why does CapacitySchedulerLeafQueueInfo have extra logic for getting
intra-queue preemption disabled status? I don't see this similar logic
elsewhere in the code.
Technically the queue CLI output changes are incompatible per

> Capacity Scheduler Intra-queue Preemption should be configurable for each

> Just as inter-queue (a.k.a. cross-queue) preemption is configurable per
> queue, intra-queue (a.k.a. in-queue) preemption should be configurable per
> queue. If a queue does not have a setting for intra-queue preemption, it
> should inherit its parents value.
