[jira] [Created] (CASSANDRA-8016) Auth tables should use higher consistency level

T Jake Luciani created CASSANDRA-8016:
-----------------------------------------

             Summary: Auth tables should use higher consistency level
                 Key: CASSANDRA-8016
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8016
             Project: Cassandra
          Issue Type: Bug
            Reporter: T Jake Luciani
             Fix For: 2.0.11


The Auth code in Cassandra uses CL.ONE or CL.LOCAL_ONE except in the case of the superuser.

Since the Auth keyspace is created with RF=1 the default experience is fine.
However if you change to RF > 1 suddenly the select statements are open to misses.

We should change reads/writes in Auth, PasswordAuthenticator, CassandraAuthorizer to always use LOCAL_QUORUM/QUORUM.

For reads if could optimize it to start with CL.ONE and on a miss increase to CL.QUORUM
