I am glad you liked it. Give it a try. The best way to learn is do soimething new. Even you are following my example , do simething different with the different datasets you rememember (like do analysis on your whatsapp, twitter or facebook data.). You can ask me about any questions related to codes. Here is the link for the dataset you are looking. https://github.com/parlad/Spark-ML/blob/master/Data/ServiceUsage.csv
