Thank you for the work. I am trying to run the program but I had no luck to get it running.
Some of the files mentioned in the instructions are not there in the repo, for example:
python twitter_stream.py
At the end I tried to run
spark-submit --jars jar/spark-streaming-kafka-assembly_2.10-1.5.1.jar recipes/trending_keywords_sparkjob.py
but I am getting this error:
