Carlo Curino commented on YARN-2664:

Matteo, thanks for picking this up. 

I tried your patch out... it is a great start, and definitely looks nicer than 
what we had there before. 

1) If I imagine visualizing many many apps, I feel it would be nice to have: 
  a) search by reservation_id (i.e., I input my reservation ID in a form and 
you show me / highlight only that)
  b) search by user id (same as above filtering by user).
2) Having the option to "gray-out" everything beside my jobs would be good 
3) I see you show both past and future (which is good) but it would be nice to 
highlight it a little more (e.g., a "now" bar, and gray background for the 
4) when reloading the page I have to re-select the plan (the form remembers the 
selection but does not show it).. it is marginally annoying.
5) We need some tests 
6) Did you tried any scale-up tests with hundreds of jobs or very jugged plans?

7) Gathering from the scheduler the "actual' resources utilized by the jobs 
running in the reservation, and visualizing them. Since you have some "past" 
tracked in the plan (needed for the CapacityOverTimePolicy), adding tracking of 
actual utilization, shouldn't be too hard, and could provide some useful 
insight to users/operators.
