Nathan Roberts created YARN-3388:
------------------------------------
Summary: 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
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.
