I applied the patch and ran few local tests.. Looks fine, I will also now go through patch and will share the thoughts. > 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 > Attachments: YARN-4108-design-doc-V3.pdf, YARN-4108-design-doc-v1.pdf, YARN-4108-design-doc-v2.pdf, YARN-4108.poc.1.patch, YARN-4108.poc.2-WIP.patch, YARN-4108.poc.3-WIP.patch > > > 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)
