Eric Payne commented on YARN-4751:
----------------------------------
[~leftnoteasy] / [~sunilg]:
YARN-3362 (Add node label usage in RM CapacityScheduler web UI) is dependent
upon parts of both YARN-3361 (CapacityScheduler side changes to support
non-exclusive node labels) and YARN-4162 (CapacityScheduler: Add resource usage
by partition and queue capacity by partition to REST API). In turn, YARN-3361
is dependent on YARN-3356 (Capacity Scheduler FiCaSchedulerApp should use
ResourceUsage to track used-resources-by-label.).
The dependencies are as follows:
- YARN-3362 depends on YARN-3361 for the new method
{{AbstractCSQueue#accessibleToPartition}}
- YARN-3362 depends on YARN-4162 for addition of the {{CapacityScheduler}}
parameter to {{CapacitySchedulerInfo}} constructor
- YARN-3361 depends on YARN-3356 for the modifications to
{{LeafQueue#canAssignToUser}}
I am not comfortable with pulling all of these changes back into 2.7,
especially the changes for non-exclusive node labels. I fear that there is a
risk of destabilization. It may be possible to rewrite YARN-3362 so that it is
not dependent on those other patches, but that seems like it could also be a
risk and a lot of time spent for the purpose of getting the GUI metrics correct.
Please let me know what approach you would like to take. If the current patch
is not an option, then we can close this JIRA as won'tfix.

> 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.
