I have a Cassandra Cluster running and we recently duplicated the cluster.
After following all the steps, the cassandra clients started failing with the following message:
"AuthenticationException(why='Username and/or password are incorrect')"
The problem is that even I can't login to the CQL shell and check the users, since it says (even with the correct username/password) that 'You have to be logged in and not anonymous to perform this request'.
When I created the Cluster I disabled the 'cassandra' superuser and now I can't do anything on my Cluster.
Is there any method to reset a user and/or password, or recreate a new superuser??
Otherwise I need to drop all the data from the cluster... Since even disabling authentication and authorization my clients give errors writting data.
