It's not a configuration error but a well known conflict between guava 12 in Spark and guava 16 in spark cassandra driver. You can find some workarounds in spark cassandra mailing list
My workaround in zeppelin is to load in zeppelin dependency loader (spark interpreter config web page) the guava 16 lib. It's a big conflict that will probably be resolved in Spark 2.0 2016-04-13 13:32 GMT+02:00 Sanne de Roever <sanne.de.roe...@gmail.com>: > Hi, > > My goal is to get Zeppelin 0.60 working with a remote Spark 1.6.1 and > Cassandra 3.4. > > The connection between Zeppelin and Spark works.
