------------------------------------------------------------------
A few notes:
* It seems like this test suite is getting a lot of copy and pasting. Looks
like we can condense most of these down to a single helper test that takes the
write and read CLs as arguments and then each test just calls the helper test.
* There's several more CLs that we aren't testing, particularly
multi-datacenter (LOCAL_QUORUM, EACH_QUORUM) (see
http://www.datastax.com/documentation/cassandra/2.0/cassandra/dml/dml_config_consistency_c.html)
* These tests may be too basic to stress test what [~tjake] was seeing, as I
doubt he was having problems reading with a mostly idle cluster.

> Consistency issue with CL.TWO
> -----------------------------
>
> Key: CASSANDRA-5460
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5460
> Project: Cassandra
> Issue Type: Test
> Affects Versions: 1.2.0
> Reporter: T Jake Luciani
> Assignee: Philip Thompson
> Priority: Minor
>
> We have a keyspace with RF=4. We write at QUORUM and read at TWO. This
> should provide consistency since writes are on 3 replicas and we read from 2,
> but in practice we don't have consistent reads.
