Zhaohui Xin commented on YARN-9277: ----------------------------------- In my opinion, preempting one container which has been running more than 10 hours is equivalent to preempt 10 containers which have been running in 1 hour. So we should preempt short-running containers firstly. [~yufeigu], [~wilfreds]. How do you think this?
