title: Incorrectly configured Cassandra cluster? Odd query results
body: <p>I have a 3 node Ec2 Cassandra cluster. Two of the nodes are set up as seeds. The keyspace is configured with a NetworkTopologyStrategy with one datacenter (us-east) and a replication factor of 3. The snitch is configured as the Ec2Snitch. If I run the same query over and over, sometimes it returns a result and other times not, which to me indicates that I've set something up incorrectly and that it is occasionally hitting a node that does not have the data on it.</p>
  
  <p>Should I have set this up differently? I'm relatively new to Cassandra and just added the two additional nodes yesterday. Up until that I was just running a one node cluster for testing purposes. Now that we are getting closer to moving into production I wanted to add some extra nodes for redundancy.</p>
