Subject [jira] [Commented] (YARN-4304) AM max resource configuration per partition to be displayed/updated correctly in UI and in various partition related metrics

Sunil G commented on YARN-4304:

Thanks Naga for the comments.

bq. 1.In the web page Max application(AM) resources for a user and queue should it not be
at partition if mentioned per partition ?
Scheduler UI displays queue inside each partition. So these resources will be per-queue per-partition.
Hence we need not have to change label explicitly stating per-partition. Make sense?

bq. Web rendering code formatting might not be needed
Yes, I also thought so earlier before doing that. But i think some times its becoming difficult
when u need add a line which cross 80 lines limit. I can change back old way if its the general

bq. existing bug in showing capacities for REST api /ws/v1/cluster/scheduler o/p when labels
were enabled. 
As of now if we see REST o/p for {{scheduler}} when used with labels, we can  easily see usedCapacity
is 0 (also others capacities). If its kept for default label , we need to make changes in
variable name atleast else it will give a wrong meaning and wrong o/p. Yes, for cases where
labels are not configured, this breaks compatibility.
I think I will segregate that issue from this and will raise a new ticket because this ticket
is getting focusing on  multiple issues. And all related discussions for this can be moved
there. Will file a new ticket shortly.

> 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
> - Update queue/partition related metrics w.r.t per-partition am-resource-percentage
