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.
