Jian He commented on YARN-4285:
-------------------------------
[~vvasudev], [~leftnoteasy], looks like the % of queue/cluster for the app does
not include reserved resources. However, the queue's used resource in the UI
does include reserved resource too. This caused the total amount of resources
for all apps in the table does not equal to the total used resource shown in
the queue.
Should we consider reserved resource too in the % of queue/cluster for an app ?
> Display resource usage as percentage of queue and cluster in the RM UI

> Currently, we display the memory and vcores allocated to an app in the RM UI.
> It would be useful to display the resources consumed as a %of the queue and
> the cluster to identify apps that are using a lot of resources.
