Overview of this book

The Sahara project is a module that aims to simplify the building of data processing capabilities on OpenStack. The goal of this book is to provide a focused, fast paced guide to installing, configuring, and getting started with integrating Hadoop with OpenStack, using Sahara. The book should explain to users how to deploy their data-intensive Hadoop and Spark clusters on top of OpenStack. It will also cover how to use the Sahara REST API, how to develop applications for Elastic Data Processing on Openstack, and setting up hadoop or spark clusters on Openstack.

Chapter 2. Integrating OpenStack Sahara

So far, we discovered in the first chapter what makes sense of the big data groove in the cloud and more specifically in OpenStack. The Elastic Hadoop on demand service called Sahara was introduced and we covered how it was architecturally integrated in OpenStack. In this chapter, we will walk through a complete setup and configuration of Sahara in OpenStack. To do so, a complete OpenStack environment setup is required in the first place before integrating Sahara.

Installing OpenStack and configuring it manually is a repetitive and sometimes an error-prone process, especially within the last releases that include more incubated projects and running more services. Getting the OpenStack environment up and running can take a few dozen pages and a lot of troubleshooting issues. On the other hand, being a proponent of the automation discipline and tools is a good step in the right direction for a fast, consistent, and correct installation process...
