As of now, we got the RDD which has the Cassandra data. We are trying to convert the RDD to DataFrame so that we can save the data to MapR-DB. We are getting following error while converting the RDD to DF.


scala> dstream.foreachRDD { rdd=>

     |  val sqlContext = SQLContext.getOrCreate(cassandraRDD.sparkContext)

     | import spark.implicits._

     | import sqlContext.implicits._

     |     val df = rdd.toDF()

     |   }

<console>:86: error: value toDF is not a member of org.apache.spark.rdd.RDD[com.datastax.spark.connector.CassandraRow]

           val df = rdd.toDF()


Please let us know, if you need more information. Thanks.
