org.apache.ambari.server.controller.spi.ResourceProvider
The resource provider allows for the plugging in of a back end data store for a resource type. The resource provider is associated with a specific resource type and can be queried for a list of resources of that type. The resource provider plugs into and is used by the {@link ClusterController cluster controller} to obtain a list of resourcesfor a given request.
