Spark Submit fails with java.lang.NoSuchMethodError: scala.Predef$.$conforms()Lscala/Predef$$less$colon$less;

The problem you are experiencing is due to the incompatibilities in Scala versions. Prebuild Spark 1.3.1 distribution is compiled with older Scala 2.10 because some of the Spark dependencies are not supported under 2.11, including JDBC support.

I would suggest to run your Spark cluster with Scala 2.10. However, if you want you can also compile your Spark package with Scala 2.11 in the following way:

dev/change-version-to-2.11.sh
mvn -Pyarn -Phadoop-2.4 -Dscala-2.11 -DskipTests clean package
