Clone an existing Hortonworks Cluster in AWS

Clone an existing Hortonworks Cluster in AWS

Contributor

Hello,

My question might sound naive but is there a way to clone an existing HDP cluster in AWS.

Using Cloud Controller, we can create a new cluster and then clone it. But is there a way to register an existing cluster in Cloud Controller and then clone it OR directly clone HDP cluster.

Hi Rinku,

I am not sure about the Cloud Controller, but if the HDP is deployed using cloudbreak then the cloudbreak will have templates/blueprints of the cluster which is deployed, which can be used to clone as many as required.

Hello @shiremath

My motive to clone is because of the configurations, user accounts and the OS changes that I have made in the existing cluster which I want in the new cluster as well. I am not sure if the template in cloudbreak would serve my purpose.

@Rinku Singh, in your case the template will not be helpful (as chnages are done in the cluster OS etc),

i think the other option would be to create an image of the cluster nodes & re-launch the image - I too agree its not a good solution.

Hi @shiremath

If I clone then I will be concerned about the ip addresses in the HDP configuration files. I am badly stuck at this point.

@Rinku Singh taking the blueprint of the existing cluster & re-playing that with new image https://cwiki.apache.org/confluence/display/AMBARI/Blueprints - considering some cleanup activity required as well on the newly launched image.
