We will now work through creating our first Spark Streaming application to illustrate some of the basic concepts around Spark Streaming that we introduced earlier.
We will expand on the example applications used in Chapter 1, Getting Up and Running with Spark, where we used a small example dataset of product purchase events. For this example, instead of using a static set of data, we will create a simple producer application that will randomly generate events and send them over a network connection. We will then create a few Spark Streaming consumer applications that will process this event stream.
The sample project for this chapter contains the code you will need. It is called scala-spark-streaming-app ...
