Wangda Tan commented on YARN-4108: ---------------------------------- Linked this to YARN-2154. > CapacityScheduler: Improve preemption to preempt only those containers that > would satisfy the incoming request > -------------------------------------------------------------------------------------------------------------- > > Key: YARN-4108 > URL: https://issues.apache.org/jira/browse/YARN-4108 > Project: Hadoop YARN > Issue Type: Bug > Components: capacity scheduler > Reporter: Wangda Tan > Assignee: Wangda Tan > > 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)). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
