java.lang.NoClassDefFoundError: kafka/common/TopicAndPartition

Question

While execution of following command in my code:

kafka_streams = [KafkaUtils.createStream(ssc, zk_settings['QUORUM'], zk_settings['CONSUMERS'][k],
                                              {zk_settings['TOPICS'][0]: zk_settings['NUM_THREADS']})
                           .window(zk_settings['WINDOW_DURATION'], zk_settings['SLIDE_DURATION'])
                 for k in range(len(zk_settings['CONSUMERS']))]

but I am getting the following error:

Am I missing something?

I was getting some spark error so I rebuilt the spark error and that lead to this error.

You should add --packages when you submit your code.

 ./bin/spark-submit --packages org.apache.spark:spark-streaming-kafka-0-8_2.11:2.2.0  <DIR>/main.py localhost:9092 test
