On HDP 2.6, appending $CLASSPATH seems to break Spark2 interpreter with:
"org.apache.zeppelin.interpreter.InterpreterException: Exception in thread "main" java.lang.NoSuchMethodError: scala.Predef$.$conforms()Lscala/Predef$$less$colon$less;"
Is the included Phoenix-Spark driver (phoenix-spark-4.7.0.2.6.1.0-129.jar) certified to work with Spark2? I thought it's the preferred way rather than via JDBC.
