             Summary: Refactor to remove ActionMetadata
                 Key: AMBARI-3536
                 URL: https://issues.apache.org/jira/browse/AMBARI-3536
             Project: Ambari
          Issue Type: Task
          Components: controller
    Affects Versions: 1.5.0
            Reporter: Oleksandr Diachenko
            Assignee: Oleksandr Diachenko
             Fix For: 1.5.0


{{ActionMetaDdata}} has hard-coded mappings of service-to-action.
* Clients per service are already indicated in the stack
* One client can be designated as a "service check" (a client should be able to NOT be defined as a service check)
* {{getActions(serviceName)}} is only called two places: one of them uses only the first element, the other checks to see if a specific string is present in the list.  This can be refactored.
* {{getClient(serviceName)}} is called only one time, and is used in {{AmbariManagementControllerImpl.addServiceCheckAction(...)}} to isolate a hostName
* {{getServiceCheckAction(serviceName)}} is called only one time and is used to see if any service has a SERVICE_CHECK action set.
