Hi [~leftnoteasy]
YARN-5889 was also to be backported to branch-2. This patch is depending on YARN-5889 as well. So I might need to backport YARN-5889 first and then this ticket. Thoughts?

> Preemption today only works across queues and moves around resources across queues per demand and usage. We should also have user-level preemption within a queue, to balance capacity across users in a predictable manner.
