I was trying to set up the user authentication for cassandra when I had the following problem.
First I have updated the cassandra.yaml
with:
authenticator: PasswordAuthenticator
then created the system_auth keyspace with a replication_factor of 3 as:
CREATE KEYSPACE system_auth WITH REPLICATION = { 'class' : 'SimpleStrategy', 'replication_factor' : 3};
Then re-ran cassandra with the command:
bin/cassandra
Then after all that, I proceeded and made sure to repair my node(s) with (though I am not sure if I understand why this is important/necessary):
nodetool repair
Even after doing all of those steps cassandra/java yells at me with:
Traceback (most recent call last):

cql.cassandra.ttypes.AuthenticationException: AuthenticationException(why='org.apache.cassandra.exceptions.UnavailableException: Cannot achieve consistency level QUORUM')
Honestly, at this point I am not sure how to proceed. If anyone has any ideas, it would be greatly appreciated.
I am running cassandra 2.0.5 in a Ubuntu vm. Not sure if that helps at all.
Also, when I run:
nodetool status
The following comes up:
nodetool status
