YunFan Zhou commented on YARN-6898:
-----------------------------------

[~Naganarasimha] Thank Naganarasimha, I think it is very useful here. Because we treat all
machines which label same node labels as a virtual cluster in our production cluster, so we
always found that our production cluster is very idle but our virtual clusters are very busy.
  And we sometimes should add some machines to the node label if the overall load of these
machines is relatively high.
If we want to see the overall load of all the machines which label same node labels, we have
to see all machines of the label. This is very inconvenient.  
So I think it is very important to display total used resources of each label in scheduler
page. 
And I also think this feature is very useful for others.

> The RM node labels page only show *Label Name*、*Label Type*、*Num Of Active NMs*、*Total
Resource*
> information of each node label, but there isn't any place for us to see the total used
resource of the node label.
> The total used resource of the node label is very important, because we can use it to
check the overall load for this
> label. We will implement it. Any suggestion?
