Allen Wittenauer updated YARN-3388: ----------------------------------- Labels: BB2015-05-TBR (was: ) > Allocation in LeafQueue could get stuck because DRF calculator isn't well > supported when computing user-limit > ------------------------------------------------------------------------------------------------------------- > > Key: YARN-3388 > URL: https://issues.apache.org/jira/browse/YARN-3388 > Project: Hadoop YARN > Issue Type: Bug > Components: capacityscheduler > Affects Versions: 2.6.0 > Reporter: Nathan Roberts > Assignee: Nathan Roberts > Labels: BB2015-05-TBR > Attachments: YARN-3388-v0.patch, YARN-3388-v1.patch > > > When there are multiple active users in a queue, it should be possible for > those users to make use of capacity up-to max_capacity (or close). The > resources should be fairly distributed among the active users in the queue. > This works pretty well when there is a single resource being scheduled. > However, when there are multiple resources the situation gets more complex > and the current algorithm tends to get stuck at Capacity. > Example illustrated in subsequent comment. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
