-ResourceManager REST API's.
-
-%{toc|section=1|fromDepth=0|toDepth=2}
-
-* Overview
-
- The ResourceManager REST API's allow the user to get information about the cluster - status on the cluster, metrics on the cluster, scheduler information, information about nodes in the cluster, and information about applications on the cluster.
-
-* Cluster Information API
-
- The cluster information resource provides overall information about the cluster.
-
-** URI
-
- Both of the following URI's give you the cluster information.
-

-* Cluster Scheduler API
-
- A scheduler resource contains information about the current scheduler configured in a cluster. It currently supports both the Fifo and Capacity Scheduler. You will get different information depending on which scheduler is configured so be sure to look at the type information.
-
-** URI
-
-------
- * http://<rm http address:port>/ws/v1/cluster/scheduler

-------
- None
-------
-
-** Capacity Scheduler API
-
- The capacity scheduler supports hierarchical queues. This one request will print information about all the queues and any subqueues they have.
- Queues that can actually have jobs submitted to them are referred to as leaf queues. These queues have additional data associated with them.

-* {Cluster Applications API}
-
- With the Applications API, you can obtain a collection of resources, each of which represents an application. When you run a GET operation on this resource, you obtain a collection of Application Objects.
-
-** URI
-
-------
- * http://<rm http address:port>/ws/v1/cluster/apps
-------
-
-** HTTP Operations Supported
-
-------
- * GET
-------
-
-** Query Parameters Supported
-
- Multiple parameters can be specified for GET operations. The started and finished times have a begin and end parameter to allow you to specify ranges. For example, one could request all applications that started between 1:00am and 2:00pm on 12/19/2011 with startedTimeBegin=1324256400&startedTimeEnd=1324303200. If the Begin parameter is not specified, it defaults to 0, and if the End parameter is not specified, it defaults to infinity.
-
-------
- * state [deprecated] - state of the application
- * states - applications matching the given application states, specified as a comma-separated list.
- * finalStatus - the final status of the application - reported by the application itself

-* Cluster Application Statistics API
-
- With the Application Statistics API, you can obtain a collection of triples, each of which contains the application type, the application state and the number of applications of this type and this state in ResourceManager context. Note that with the performance concern, we currently only support at most one applicationType per query. We may support multiple applicationTypes per query as well as more statistics in the future. When you run a GET operation on this resource, you obtain a collection of statItem objects.
-
-** URI
-
-------
- * http://<rm http address:port>/ws/v1/cluster/appstatistics
-------
-
-** HTTP Operations Supported
-
-------
- * GET
-------
-
-** Query Parameters Required
-
- Two paramters 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.

-
- The Submit Applications API can be used to submit applications. In case of submitting applications, you must first obtain an application-id using the {{{Cluster_New_Application_API}Cluster New Application API}}. The application-id must be part of the request body. The response contains a URL to the application page which can be used to track the state and progress of your application.

-
-** POST Response Examples
-
- POST requests can be used to submit apps to the ResourceManager. As mentioned above, an application-id must be obtained first. Successful submissions result in a 202 response code and a Location header specifying where to get information about the app. Please note that in order to submit 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.
-
- Please note that this feature is currently in the alpha stage and may change in the future.
