I had a similar error but it was due to authentication. Are you using authentication on the cassandra cluster? In case you have, you'll need to set up cqlshrc on each pod with the [authentication] section so that when cain execs it can connect to the cluster.

yes, I use authentication on Cassandra. Can you please how should I implement this??

Cain execs onto the Cassandra pods and uses cqlsh commands so the credentials need to be set up.

You'll need to add an init script to your helm chart which will load your credentials from a secret and populate the file mentioned above. Documentation for configuration.
