Hi, I have setup a 16 node cluster (8 per DC; C* 2.2.4) up and running in our production setup. We use Datastax Java driver 2.1.8.
I would like to set up Authentication and Authorization in the cluster without breaking the live clients. >From the references I found by googling, I can setup credentials for a new cluster. But it is not clear to me what steps I should take for setting up credentials in an already running cluster without breaking existing clients. Can someone clarify me or link me to a reference I may have missed? I'd really appreciate it. Thank you, Vigneshwaran
