MENG DING commented on YARN-4108:
---------------------------------
Hi, [~leftnoteasy], will there be a separate ticket to track the issue of
selecting to-be-preempted containers based on pending new/increase resource
request?
> CapacityScheduler: Improve preemption to preempt only those containers that
> would satisfy the incoming request
> --------------------------------------------------------------------------------------------------------------

> This is sibling JIRA for YARN-2154. We should make sure container preemption
> is more effective.
> *Requirements:*:
> 1) Can handle case of user-limit preemption
> 2) Can handle case of resource placement requirements, such as: hard-locality
> (I only want to use rack-1) / node-constraints (YARN-3409) / black-list (I
> don't want to use rack1 and host\[1-3\])
> 3) Can handle preemption within a queue: cross user preemption (YARN-2113),
> cross applicaiton preemption (such as priority-based (YARN-1963) /
> fairness-based (YARN-3319)).
