Krisztian Horvath updated YARN-2248:
------------------------------------
Attachment: YARN-2248-3.patch
The order of the live container resource release is important as the user can
go under Resource usage <0, 0>. To avoid it changed the order. More metrics
test added.

> 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:
