---------------------------------------
Hi Jeff,
In point 1. The blueprint that is created. The host groups 'worker' and
'master' were already present in the previous blueprint or those are new
hostgroups.
> Add support for "add hosts" specifying host name, blueprint name and host
> group name

>
> 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.
> {code}
