Hi Ashan, Can you tell us the CEP version you are using?
A similar error was reported for CEP-4.0.0-M5 in [1], but was fixed for the CEP-4.0.0-Alpha pack. Also, better if you can share the full configuration. Are you using the embedded cassandra within CEP with the default configurations? AFAIR, the default configs used admin:admin as the credentials for embedded cassandra. Looking at the stack trace, it seems hector was trying to create a client connection and failed, and when trying to throw the exception, encountered a NoClassDef error. So the original cause might be a configuration issue, that is hidden by the NoClassDef error.
