Wangda Tan updated YARN-6124:
-----------------------------
Attachment: YARN-6124.wip.1.patch
Attached WIP patch to demonstrate what I plan to do:
We will add a PCPP to schedulingMonitor no matter under any case. And it will
periodically check if any reinitialize happens on CS side, if reinitialize
happens and preemption enabled, it will sync latest preemption configs and
refresh its local state.
> Make CapacityScheduler Preemption Config can be enabled / disabled / updated
> without restarting RM

> Now enabled / disable / update CapacityScheduler preemption config requires
> restart RM. This is inconvenient when admin wants to make changes to
> preemption config.
