Hi Naga, Jonathan is correct, the Blueprints processor requires that the ambari-agents be installed and registered.
If you are using Ambari 2.1.0 or later, you could potentially install the agents manually, and the Blueprints processor will detect this and start the deployment process on each host as it comes online. If you already have a set of hosts you wish to deploy to, it’s generally better to have the agents up and running on each node prior to a Blueprints deployment.

I could see the background operation (Logical Request: Provision Cluster) running in Ambari UI. But, the background operation is in a hung state. I am wondering whether that is due to missing information (ssh key and login user, as we provide them during manual install using Ambari UI). Can you please clarify?

Assuming you have two host groups, here’s an example of what to POST. You also need to specify the blueprint name of the blueprint you created.

The “href” and “items” elements are only for informational and structure purposes; you wouldn’t want to include them in a POST going back to the server. What are you trying to do with your cluster? Chances are you just need to omit the fields it’s complaining about.
