Zhijie Shen updated YARN-1001:
------------------------------
Attachment: YARN-1001.1.patch
I created a patch, which add a new RESTful API:
{code}
http://<rm http
address:port>/ws/v1/cluster/appscount?states=state1,state2&types=type1,type2
{code}
Bellow is the example response in JSON format:
{code}
{
"appsCount":
{
"countItems":
[
{"state":"accepted","type":"other","count":1},
{"state":"accepted","type":"mapreduce","count":1},
{"state":"finished","type":"other","count":0},
{"state":"finished","type":"mapreduce","count":1}
]
}
}
{code}
Three aspects need to be clarified:
* The combination bucket that has 0 apps is listed as well
* State and type matching ignores the case.
* Two forms of params are allowed for both types and states:
states=state1&states=state2,state3&types=type1&types=type2,type3
> 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.
