Srimanth Gunturi commented on YARN-1001:
----------------------------------------
[~zjshen], yes we could filter by app-type + state and count. But this is very
inefficient as the number of applications could be large with potentially
paging involved. We dont want to read the huge outputs just to get the counts.
It would be helpful if state-counts per app-type be provided.
> YARN should provide per application-type and state statistics

> In Ambari we plan to show for MR2 the number of applications finished,
> running, waiting, etc. It would be efficient if YARN could provide per
> application-type and state aggregated counts.
