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 6. Hadoop High Availability Using Sahara

Ultimately, ensuring a high available system might need a large investment of time and expertise. Without a doubt, building a Hadoop cluster requires more crucial configuration steps in order to respond properly in the event of failure. At this point, installing and configuring manually a high available Hadoop cluster might be an error-prone process. In addition, adopting a HA solution in a Hadoop cluster needs more expertise on different processes that need a customized setup. The difficulty of such a setup might vary from one Hadoop plugin cluster to another. However, it is more practical to simplify the HA deployment setup using Sahara. This chapter will cover how to deploy easily a high available Hadoop cluster without going through any other third-party tool or solution. On the other hand, it is important to note that the latter setup is only limited to HDP and CDH plugins in Sahara.
