Queries and inserts fail on 2 node cluster when replication factor is specified.
--------------------------------------------------------------------------------

                 Key: CASSANDRA-2969
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-2969
             Project: Cassandra
          Issue Type: Bug
          Components: Core
    Affects Versions: 0.8.2
         Environment: 2 node Cassandra cluster with both nodes up and running. The replication
factor is specified and can be 1 or 2. Client is using Hector. For production, I want to use
a RF of 2 so the data is stored on both nodes and use a CL of ONE for reads and writes.
            Reporter: Andy Klages


When a query or insert is performed, I get the following exception:

me.prettyprint.hector.api.exceptions.HUnavailableException: : May not be enough replicas present
to handle consistency level.

I've tried consistency levels ANY, ONE, and QUORUM, but to no avail. I'm assuming it would
do this for the other levels too.

Running the "get" and "set" commands on cassandra-cli always return "null" so it's encountering
the same problem.

Note that I don't get this problem when the keyspace doesn't have replication_factor specified.
But I need the data replicated on both nodes which is why I'm specifying the RF.
