Answer 1

This is an issue with version of the cassandra-driver-core jar's dependency.

The provided cassandra's version is 2.0
The provided cassandra-driver-core jar's version is 2.1.5

The jar should be the same as the version of the cassandra running.

In this case, the included jar file should be cassandra-driver-core-2.0.0.jar
