This chapter is dedicated to guiding you through the steps to set up the environment for the execution of a Storm topology. The intent is to prepare the user sandbox and get you steered toward executing some of the sample code and understanding the working of various components. All the concepts will be accompanied by code snippets and a "try it yourself" section so that you are equipped to understand the components in a practical manner and are ready to explore and harness the power of this wonderful technology.
The topics that will be covered in this chapter are as follows:
Storm topology and components
Executing the sample Storm topology
Executing the topology in distributed mode
By the end of the chapter, you will be able to understand the components and data flow in a topology, understand the simple word count topology, and execute it in the local and distributed modes. You will also be able to tweak the starter project topologies to add...
