Subject [jira] [Updated] (YARN-2664) Improve RM webapp to expose info about reservations.

Matteo Mazzucchelli updated YARN-2664:
    Attachment: YARN-2664.2.patch

Hi Carlo.
I submitted a new patch. I followed your suggestions to improve the work.

6) Did you tried any scale-up tests with hundreds of jobs or very jugged plans?
I tried with one hundred jobs, more or less. I'm going to try with even more jobs.

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.
I have an idea how to make it. I'll let you know

Exposing this through the webapp GUI is important.
