Zhijie Shen commented on YARN-1001:
-----------------------------------
Then, the limitation of this requirement is that the dimension of the params to
categorize the applications is not free to scale. If you want add one more
para, the number of buckets will be increased exponentially. Therefore, I'm
afraid this proposed API cannot support as many params as getApps() can do.
@Srimanth Gunturi, do you think application type and state are enough for
Ambari?
> YARN should provide per application-type and state statistics

> In Ambari we plan to show for MR2 the number of applications finished,
