Ambari Blueprints are definition of your HDP cluster in “JSON” format, it contents information about all the hosts in your cluster, their components, mapping of stack components with each hosts or hostgroups and other cool stuff. Using Blueprints we can call Ambari APIs to completely automate HDP installation process. Interesting stuff, isn’t it ?
Lets get started with single node cluster installation. Below are the steps to setup single-node HDP cluster with Ambari Blueprints.
Note - For Ambari 2.6.X onwards, we will have to register VDF to register internal repository, or else Ambari will pick up latest version of HDP and use the public repos. please see below document for more information. For Ambari version less than 2.6.X, this guide will work without any modifications.
