Spark Streaming and Mllib

In my first post on Spark Streaming, I described how to use Netcast to emulate incoming stream. But later I found this question on StackOverflow. In one of the answer, there’s a piece of code which shows how to emulate incoming stream programmatically, without external tools like Netcat, it makes life much more comfortable. In this post, I describe how to fit a model using Spark’s MLlib, and then use it on the incoming data, and save the result in a parquet file.
