Mayank Bansal updated YARN-2113: -------------------------------- Description: Preemption today only works across queues and moves around resources across queues per demand and usage. We should also have user-level preemption within a queue, to balance capacity across users in a predictable manner. (was: This is different from (even if related to, and likely share code with) YARN-2069. YARN-2069 focuses on making sure that even if queue has its guaranteed capacity, it's individual users are treated in-line with their limits irrespective of when they join in. This JIRA is about respecting user-limits while preempting containers to balance queue capacities.) > Add cross-user preemption within CapacityScheduler's leaf-queue > --------------------------------------------------------------- > > Key: YARN-2113 > URL: https://issues.apache.org/jira/browse/YARN-2113 > Project: Hadoop YARN > Issue Type: Sub-task > Components: scheduler > Reporter: Vinod Kumar Vavilapalli > Assignee: Vinod Kumar Vavilapalli > Fix For: 2.5.0 > > > Preemption today only works across queues and moves around resources across > queues per demand and usage.
