Integration of Apache Spark and Apache Kafka using PySpark

Integration of Apache Spark and Apache Kafka using PySpark



I want to send messages from kafka to Spark and then use Spack SQL for from manupulation. Finally i want to send it to another Kafka topic.

When i use 

kvs = KafkaUtils.createStream(ssc,"localhost:2181", "spark-streaming-consumer", {topic:1})
it creates TransformedDStream. Then i am not able to convert it to Dataframes so can use SparkSQL in it.
Later when i refered and tried the following to get a dataframe
df = spark.readStream.format("kafka").option("kafka.bootstrap.servers","localhost:9092").option("subscribe", "SparkPublish").load()

Even after this i am getting different errors.

Can anyone tell me how can receive a message from kafka using Spark streaming as Dataframes and use SparkSQl on it?

Thank You.
