Description

`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:
