Could you re-run the Spark Connector (Scala) notebook it's in entirety and change the JARs configuration to include all four JARs? Could you also include updating the PySpark version? Thanks!

@tknandu Oh and I forgot to note that the DocumentDB version of the notebook doesn't need to change as we'll deprecate this per #87 - thanks!
