Krisztian Horvath commented on YARN-2248:


As long as we don't break the functionality we can merge them and try to take 
the best out of them, so yes. Have you tried your patch with the queue metrics 
test, yet?

> We would like to have the capability (same as the Fair Scheduler has) to move 
> applications between queues. 
> We have made a baseline implementation and tests to start with - and we would 
> like the community to review, come up with suggestions and finally have this 
> contributed. 
> The current implementation is available for 2.4.1 - so the first thing is 
> that we'd need to identify the target version as there are differences 
> between 2.4.* and 3.* interfaces.
> The story behind is available at 
> http://blog.sequenceiq.com/blog/2014/07/02/move-applications-between-queues/ 
> and the baseline implementation and test at:
