Vishy Kasar commented on CASSANDRA-8016:
----------------------------------------
We need to fallback to CL.LOCAL_QUORUM also in case of CL.LOCAL_ONE failure (as
opposed to miss)
> 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
> Assignee: Aleksey Yeschenko
> 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 we could optimize the code to start with CL.ONE and on a miss
> increase to CL.QUORUM
