Hello,

I'd like to try the cassandra tutorial example: https://github.com/zznate/cassandra-tutorial
 by following the readme.

After typing  mvn -e exec:java -Dexec.args="get" -Dexec.mainClass="com.datastax.tutorial.TutorialRunner"
I got the following errors.
Should I do something before the above command?
Thanks.

+ Error stacktraces are turned on.
