             Summary: Add support for "add hosts" specifying host name, blueprint name and host group name 
                 Key: AMBARI-8458
                 URL: https://issues.apache.org/jira/browse/AMBARI-8458
             Project: Ambari
          Issue Type: Improvement
            Reporter: John Speidel
            Assignee: John Speidel
             Fix For: 2.0.0


Provide a higher level api for host provisioning.
This api will accept a host name, blueprint name and host group.
The result of this api call will be fully operational hosts added to the existing cluster with configuration and components which are defined in the specified blueprint/host_group.  All components on the added hosts will be installed and started.

All hosts must be reachable via ambari server and have the ambari agent running and registered with the ambari server prior to using this api.  

This is an asynchronous api so it will return the standard asynchronous response.
