Craig Welch commented on YARN-2496:
-----------------------------------
LeafQueue.java
I think there’s a bug in the way a user’s consumed value is obtained when
working with labels (it’s unchanged from the existing behavior, but it needs to
change, I think) The consumed is going to be for all jobs regardless of lable
regardless of label expression but it’s being subtracted from a value which is
limited to the user expression, so - this could be incorrect if user has some
jobs w/out labels and some with (or with different labels) in the same queue.
Jobs using labels could be starved due to jobs running under the same user with
other labels. I believe consumed resources needs to be per label and/or label
expression.

> This JIRA Includes:
> - Add/parse labels option to {{capacity-scheduler.xml}} similar to other
> options of queue like capacity/maximum-capacity, etc.
> - Include a "default-label-expression" option in queue config, if an app
> doesn't specify label-expression, "default-label-expression" of queue will be
> used.
> - Check if labels can be accessed by the queue when submit an app with
> labels-expression to queue or update ResourceRequest with label-expression
> - Check labels on NM when trying to allocate ResourceRequest on the NM with
> label-expression
> - Respect labels when calculate headroom/user-limit
