I used to use calliope, which was really awesome before DataStax native integration with Spark. Now I'm quite happy with the official DataStax spark connector, it's very straightforward to use.
I never tried to use these drivers with Java though, I'd suggest you to use them with Scala, which is the best option to write spark jobs.
