Nathan Roberts updated YARN-3388: --------------------------------- Attachment: YARN-3388-v0.patch Initial patch for comments on approach. Seems to work well in basic testing on 2.6. I don't know how this interacts with label support + userlimit which I think is still lacking in some cases anyway. Hoping [~leftnoteasy] and others can comment. > userlimit isn't playing well with DRF calculator > ------------------------------------------------ > > 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 > Attachments: YARN-3388-v0.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)
