A nifi cluster has been created using a CloudFormation script. The cluster is running, and the customer now wishes to scale up the cluster by adding a node. What is the optimal way to add a node to a running nifi cluster established through CloudFormation? My instinct tells me to do it within the confines of CloudFormation so that the new node isn't lost if CloudFormation is re-run. But does that mean the active cluster needs to be shutdown just to modify the CloudFormation scripts and restart it with the new cluster configuration?
Has anyone successfully done this, and can offer some tips or a link to an outline of the process?
