----------------------------------

             Summary: Capacity Scheduler changes for moving apps between queues
                 Key: YARN-2248
                 URL: https://issues.apache.org/jira/browse/YARN-2248
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: capacityscheduler
            Reporter: Janos Matyas
            Priority: Minor


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:
