Subject Re: C* 3 node issue -Urgent

The cassandra user requires QUORUM consistency to be achieved for
authentication. Normal users only require ONE. I suspect your system_auth
keyspace has an RF of 1, and the node that owns the cassandra users data is

Steps to recover:
1. Turn off authentication on all the nodes
2. Restart the nodes and make sure they are UN
3. Alter system_auth to have a higher RF than 1 (3 is probably appropriate)
4. Turn auth back on and restart
5. Create a new user and use that from now on.
