Srimanth Gunturi commented on YARN-1001:
----------------------------------------
[~zjshen], we are expecting {{/ws/v1/cluster/appscount}} to provide all
app-types/state-counts in 1 call.
We are expecting {{/ws/v1/cluster/appscount?types=mapreduce}} to provide all
mapreduce state-counts in 1 call.
Apart from that, we need {{/ws/v1/cluster/appscount}} information pushed to
Ganglia. Or else Ambari will not be able to show various graphs which are
important. We currently populate
{{/etc/hadoop/conf/hadoop-metrics2.properties}} file telling RM to push to
Ganglia (resourcemanager.sink.ganglia.servers).
> 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.
