In previous post we have seen how to install multi node HDP cluster using Ambari Blueprints. In this post we will see how to Automate HDP installation with Namenode HA using 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.
Note - I have kept Namenodes on prodnode1 and prodnode3, you can change it according to your requirement. I have added few more services like Hive, Falcon, Oozie etc. You can remove them or add few more according to your requirement.
Step 4: Create an internal repository map
4.1: hdp repository – copy below contents, modify base_url to add hostname/ip-address of your internal repository server and save it in repo.json file.
