Sunil G commented on YARN-4945: ------------------------------- Thanks [~eepayne] for the detailed comments. Agreeing to the comments mostly. I will update them in next patch. Few doubts or clarifications for below comments. bq.It doesn't make sense to me to limit intra-queue preemption based on how much of the queue's guaranteed resources are used. I will try explain here. For queue, if there are plenty of resources unused (guaranteed - used > 70%), then pending apps can get certain amount of resources mostly (priority/user-limit etc). We can think on a safe default limit here. Still this is per-queue only.
