Cluster tuning parameters for provisioning Ambari-managed HDP Cluster via blueprint

avatar
Expert Contributor

I have used a blueprint to provision an HDP cluster in the following conditions:

- Create an Ambari-managed HDP cluster in a manual approach (Non-blueprint installation)

- Extract blueprint from the created cluster.

- Remove all non-generic parts and all tuning part from the extracted blueprint to make it more generic.

- Create host-group mapping file to capture all passwords and hostnames.

- Create another cluster with the modified blueprint and host-group mapping file.

My question is when you are using a manual installation Ambari selects the recommended values for tuning parameters. However, in the blueprint installation, you need to modify them separately or put all parameters in host-group mapping file which make the blueprint maintenance very hard. I was wondering whether there is another way that Ambari can pick all the parameters in the same way that is used in a Non-blueprint installation.
