Oliver, I have been unable to reproduce this issue using the cpp-driver against a locally created Apache Cassandra cluster using CCM with proper modifications to enable GosspingPropertyFileSnitch using the data centers and racks defined by the `nodetool status` information provided. I would suggest using CQLSH to query every nodes `system.local` and `system.peers` tables to make sure they all have the same `data_center` attribute defined as expected.
NOTE: The only way that I was able to reproduce the issue using the default data center aware with token awareness was to provide an invalid data center name during the keyspace creation; however that is to be expected since that data center would not exist or be known to the cluster. ~Fero Michael Fero
