Thank you, Manjot, for providing such a sharp analysis of the potential cause for the
Cassandra connection error. The suspicion that the older driver (2.2.0-rc3.jar) is

troubleshooting process requires meticulousness no different from timing your moves
perfectly to overcome an extremely fast segment in
