title: Unable to insert data from Spark to Cassandra
body: <p>When I try to insert a record using this code</p>
  
  <pre><code>val myRdd = sc.cassandraTable("mykeypace", "mytable")
  val myTransformedRdd = myRdd.map {
    ( myRdd.getString("field1"), myRdd.GetString("field3") )
  }
  myTransformedRdd.saveToCassandra("mykeyspace", "someothertable", 
  SomeColumns("field1", field3"))
  </code></pre>
  
  <p>I encounter the following error:</p>
  
  <pre><code>value GetString is not a member of com.datastax.spark.connector.rdd.CassandraTableScanRDD[com.datastax.spark.connector.CassandraRow]
  </code></pre>
  
  <p>What can this be?</p>
