> 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)).
