Yes, it's incompatible. From the java-driver 2.0 requirements:
The driver uses Casandra's native protocol, and this version 2.0 uses the second version of that protocol. As such, this version of the driver requires a version of Cassandra greater than or equal to 2.0 (for Cassandra 1.2 please use the version 1.0 of the driver).
Try downgrading to 1.0, latest version is 1.0.4:
<dependency>
<groupId>com.datastax.cassandra</groupId>
<artifactId>cassandra-driver-parent</artifactId>
<version>1.0.4</version>
</dependency>
