Wangda Tan created YARN-3515: -------------------------------- Summary: Support intra-queue non-exclusive container allocation within a LeafQueue Key: YARN-3515 URL: https://issues.apache.org/jira/browse/YARN-3515 Project: Hadoop YARN Issue Type: Sub-task Reporter: Wangda Tan Assignee: Wangda Tan
Related to YARN-2498: YARN-2498 addressed the problem of non-exclusive container preemption in inter-queue level. When a queue over-satisfied on a given partition, ignore_partition_exclusivity containers will be preempted first. But it is possible that when a queue is under its guaranteed resource, there's pending resources for a given partition, and resources being used by ignore_partition_exclusivity containers. For example: - App1/App2 in queue-A, app1 wants 30 partition=x containers and app2 uses 30 partition=x ignore_partition-exclusivity containers. It is possible we need reclaim resource from app2 for partition=x. Relation between this and YARN-2498 is similar to relation between YARN-2069 and YARN-2113. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
