In this chapter, we have installed OpenStack using the Packstack tool. Sahara has been successfully integrated and it is possible to instruct the Elastic Data Processing component in OpenStack using either the command-line interface or via Horizon.

Before walking through the rest of the chapters, it might be essential to have the OpenStack environment up and running without any issues. As has been described in Chapter 1, The Essence of Big Data in the Cloud, the Sahara service depends on other services and components of OpenStack. To run a Hadoop cluster, spin nodes, and run jobs, different services in OpenStack are involved. This will be covered in more detail in the next chapter, where we will examine the workflow of creating a Hadoop cluster in OpenStack using Sahara.
