Daniel Templeton commented on YARN-7022:
----------------------------------------
That's my read of it. I find the new UI counter-intuitive in that no other UIs
I use trigger an action based on a hover. With the new UI I always click on
the queue to select it and then have to use the back button to get back because
clicking unexpectedly takes me to the queue-specific page. In a UI, the
general contract is that hover gives pop-up info, click selects, and
double-click enters.

> Currently, the behavior of interacting with the tree view in the queues tab
> of the UI is difficult in that you must mouse over to select a queue node and
> then click to drill down. It would be more intuitive to single click to
> select a different queue and double-click to drill down instead.
