----------------------------------
Hi [~sunilg],
Took a look at REST API implementation of latest patch, some comments:
By design, PartitionResourcesInfo/ResourcesInfo should be used by
user/queue/app, so we need to make fields and usage generic to these components.
- amResourceLimit is meaningful to all components. App doesn't use that field
for now, but we can keep it and set it to infinite.
- userAMResourceLimit is not meaningful to queue/app, and it's overlap to
user.resourcesInfo.amResourceLimit, I suggest to remove it and we can use
amResourceLimit of first user of queues to show on UI. Another reason is in the
future we could have different users has different amResourceLimits.
And also ResourcesInfo is RESTful mapping to ResourceUsage, so necessary
changes need to be added to ResourceUsage (Maybe rename ResourceUsage to
ResourcesInformation?) as well. Renaming could be done in a separated JIRA, but
I suggest to change ResourceUsage implementation at the same JIRA.
If you agree with above, ResourcesInfo's constructor shouldn't relate to
LeafQueue and considerAMUsage, it should simply copy fields from ResourceUsage.

> As we are supporting per-partition level max AM resource percentage
> configuration, UI and various metrics also need to display correct
> configurations related to same.
> For eg: Current UI still shows am-resource percentage per queue level. This
> is to be updated correctly when label config is used.
> - Display max-am-percentage per-partition in Scheduler UI (label also) and in
> ClusterMetrics page
> - Update queue/partition related metrics w.r.t per-partition
> am-resource-percentage
