Sunil G commented on YARN-4945: ------------------------------- Thanks [~eepayne], I think the scenario makes sense to me. And as earlier discussed, an ideal order of "preemption to help for better resource distribution" can be in follow order {{InterQueue => FiFoIntraQueue (User-limit => priority) => etc }} . So within a queue, user-limit will have the first say. And i think it can be incorporated to existing design with minimal refactoring. > [Umbrella] Capacity Scheduler Preemption Within a queue > ------------------------------------------------------- > > Key: YARN-4945 > URL: https://issues.apache.org/jira/browse/YARN-4945 > Project: Hadoop YARN > Issue Type: Bug > Reporter: Wangda Tan > Attachments: Intra-Queue Preemption Use Cases.pdf, > IntraQueuepreemption-CapacityScheduler (Design).pdf, YARN-2009-wip.2.patch, > YARN-2009-wip.patch, YARN-2009-wip.v3.patch, YARN-2009.v0.patch, > YARN-2009.v1.patch, YARN-2009.v2.patch, YARN-2009.v3.patch > > > This is umbrella ticket to track efforts of preemption within a queue to > support features like: > YARN-2009.
