Let me clarify: we just recently implemented Spark-Cassandra connector in Scala, basing on the previous similar work done for Hadoop-Cassandra in Java and the reduction in size was about 3x and up to 5x in concurrent code; however it is still hard to measure properly, because the new driver offers more functionality than the original. Of course YMMV, but writing in Scala is not just getting rid of meaningless boilerplate.
