Eric Payne updated YARN-4751:
-----------------------------
Attachment: YARH-4752-branch-2.7.002.patch
Attaching {{YARH-4752-branch-2.7.002.patch}}. It addresses some of the
checkstyle warnings. The findbugs warning is regarding {{ZKRMStateStore}},
which version 001 of this patch didn't change. This false findbugs warning
looks to be documented in YARN-4328.
Regarding unit tests, I have been trying to decide the best approach. I would
like to start up a MiniYARNCluster in order to get as close to a labeled
environment so that this patch can be tested. However, starting up a
MiniYARNCluster, configuring multiple nodes, configuring multiple queues,
configuring labels, and launching containers on both labeled and non-labeled
queues will be a lot of testing overhead for a patch that will only be
integrated into 2.7. There are a couple of unit tests that could be used as
models, but I don't see anything that already does what would be needed.
[~sunilg] and [~jlowe], I would appreciate your opinion on the best unit test
approach.

> In 2.6 and 2.7, the capacity scheduler UI does not have the queue graphs
> separated by partition. When applications are running on a labeled queue, no
> color is shown in the bar graph, and several of the "Used" metrics are zero.
