Two paramters can be specified. The parameters are case insensitive.
Two parameters can be specified. The parameters are case insensitive.
* states - states of the applications, specified as a comma-separated list. If states is not provided, the API will enumerate all application states and return the counts of them.
* applicationTypes - types of the applications, specified as a comma-separated list. If applicationTypes is not provided, the API will count the applications of any application type. In this case, the response shows * to indicate any application type. Note that we only support at most one applicationType temporarily. Otherwise, users will expect an BadRequestException.

Cluster Application State API
-----------------------------
With the application state API, you can query the state of a submitted app as well kill a running app by modifying the state of a running app using a PUT request with the state set to "KILLED". To perform the PUT operation, authentication has to be setup for the RM web services. In addition, you must be authorized to kill the app. Currently you can only change the state to "KILLED"; an attempt to change the state to any other results in a 400 error response. Examples of the unauthorized and bad request errors are below. When you carry out a successful PUT, the iniital response may be a 202. You can confirm that the app is killed by repeating the PUT request until you get a 200, querying the state using the GET method or querying for app information and checking the state. In the examples below, we repeat the PUT request and get a 200 response.

You can confirm that the app is killed by repeating the PUT request until you get a 200, querying the state using the GET method or querying for app information and checking the state. In the examples below, we repeat the PUT request and get a 200 response.
Please note that in order to kill an app, you must have an authentication filter setup for the HTTP interface. The functionality requires that a username is set in the HttpServletRequest. If no filter is setup, the response will be an "UNAUTHORIZED" response.
