Naganarasimha G R commented on YARN-3362:
-----------------------------------------

Thanks [~wangda],
Regarding the approach to display i had few concerns : 
* There will be some common queue metrics across the labels, wont it get 
repeated across for each label if a queue is mapped to multiple labels ?
* IIUC most of the queue Metrics might not be specific to a label, like 
Capacity, Absolute max capacity, Max apps, Max AM's per user etc... . Correct 
me if my understanding on this is wrong.
* Apart from the label specific queue metrics like (label capacity, label abs 
capacity,used) are there any new Label specific queue metrics you have in your 
mind ?
* would it be better to list like
{noformat}
+ root [=====================] 30% used
  + a  [=======================================] 75% used
    + a1 [=================]  30% used
               ---------------------------------------------
              |          Queue Metrics                     |
              |--------------------------------------------|
              |       metrics1       |            value1   |
              |       metrics2       |            value2   |
           ---------------------------------------------
              |          Active Users info  (yarn-3273)    |
              |--------------------------------------------|
              |       user1       |            info        |
              |       user2       |            info        |
           ---------------------------------------------
              |     Label Resource usage info              |
              |--------------------------------------------|
              | label_x  [=====================] 30% used  |
              | label_y  [================] 20% used       |
              ----------------------------------------------
    + a2 [=================]  30% used
    ...
{noformat}
* Also if required we can have seperate page (/in the labels page/append at the 
end of CS page) like :
{noformat}
+ label_x  [=====================] 30% used [Actual Resource - Used resource ]
        + root [=====================] 30% used [Actual Resource - Used 
resource ]
          + a  [=======================================] 75% used [Actual 
Resource - Used resource ]
            + a1 [=================]  30% used [Actual Resource - Used resource 
]
+ label_y
    + root [...]
    + ...
+ label_z
    + root [...]
{noformat}

YARN-3273, has added more info to the CS page so we need to consider the size 
of page and its usability.
Please provide your thoughts on the same
