----------------------------------
Summary: Expose demand at the queue level for FairScheduler
Key: YARN-5056
URL: https://issues.apache.org/jira/browse/YARN-5056
Project: Hadoop YARN
Issue Type: Improvement
Affects Versions: 2.7.2
Reporter: Daniel Weeks
Priority: Minor
There currently isn't a way to determine where demand is coming from within the
scheduler. Issues like YARN-2408 proposed a more detailed way to expose this
information, but it's very easy to expose this at a queue level by simply
including the queue demand, which is a good indicator of where resources
requests are coming from (at least at the queue level).
This will help to better understand metrics like "containersPending" and where
resource requests are originating.
