Sunil G commented on YARN-5293:
-------------------------------
Adding to what [~Naganarasimha Garla] has mentioned and based on the example
mentioned in the description, label A may also be used in some other queue's.
So if we are disabling for a label, then we may automatically disable
preemption for some other queues automatically. I think think we need to define
the order of disabling in correct way. Do we see any other use case advantages
of disabling preemption per label? I think its better if we can carefully look
into with more usability aspects also. Else this may add more complexity for
user.

> Key: YARN-5293
> URL: https://issues.apache.org/jira/browse/YARN-5293
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Jonathan Hung
>
> [YARN-2056|https://issues.apache.org/jira/browse/YARN-2056] added support for
> disabling preemption at queue level.
> [YARN-2498|https://issues.apache.org/jira/browse/YARN-2498] added support for
> per partition preemption. It would be useful to be able to disable preemption
> per partition per queue, so that if a queue Q has access to two labels A and
> B, we can disable preemption for Q in A but not in B.
