             Summary: Add ability to export a blueprint from a running cluster 
                 Key: AMBARI-4786
                 URL: https://issues.apache.org/jira/browse/AMBARI-4786
             Project: Ambari
          Issue Type: New Feature
            Reporter: John Speidel
            Assignee: John Speidel
             Fix For: 1.5.0


Export a blueprint for a running cluster using an alternate rendering for the cluster resource.

api/v1/clusters/c1?format=blueprint

For this change, the blueprint will be very minimal and will only contain node groups and no configuration.  Subsequent patches will introduce configuration and other cluster data.
