  <p>Two jar files are added. spark-cassandra-connector-java-assembly-1.4.0-M1-SNAPSHOT.jar &amp; spark-core_2.10-0.9.0-incubating.jar. spark-cassandra-connector-java-assembly-1.4.0-M1-SNAPSHOT.jar is build against scala 2.10. 
  Typing scala -version on command prompt showing scala code runner version 2.11.6. Accessing spark from spark-shell have no issue. Even access in cassandra column family from spark-shell is working fine.</p>
