What should I do in OpsCenter after deleting the cassandra superuser?

Question

After building a DSE cluster with Opscenter, I cannot configure after deleting the cassandra user. I see an error code that Opscenter is trying to log in to the DSE cluster with the cassandra user. What operation should I do in Opscenter after deleting the cassandra user? Please tell me.

You haven't provided a lot of information and I don't know what the problem is exactly but I'm going to assume that you enabled authentication on your DSE cluster.

In order to disable or drop the default cassandra superuser role, you need another superuser role to do that so I take it you've created a new superuser role.

Using the new superuser role, you need to create separate logins for users and applications. You should create a separate service account for OpsCenter. Once you've done that, you need to update the cluster connection properties in clusters/cluster_name.conf on the OpsCenter with the new credentials:

[cassandra]
username = opsc_svc_account
password = opsc_svc_account_password
