authentication in Cassandra 3.0 is broken

Question

On a new installation of cassandra 3.0.20 on redhat 7 I can not list roles. I have tried the option of fixing /etc/alternatives/cassandra/cassandra.yaml with...

authenticator: PasswordAuthenticator

and then restart the service.

still when I run a simple command like LIST ROLES I get the following error.

cassandra@cqlsh> list roles;

Unauthorized: Error from server: code=2100 [Unauthorized] message="You have to be logged in and not anonymous to perform this request"

Answer 1

It turns out that systemctl was not completely stopping cassandra due to weirdness with Redhat 7 and the init file. Therefore the changes to my cassandra.yaml were not taking effect.

Once I killed cassandra, made a proper cassandra.service and restarted the desired settings took effect, and I am able to run operations like "LIST ROLES;"normally.
