Overview of this book

<p>We are facing an avalanche of data. The unstructured data we gather can contain many insights that could hold the key to business success or failure. Harnessing the ability to analyze and process this data with Hadoop is one of the most highly sought after skills in today's job market. Hadoop, by combining the computing and storage powers of a large number of commodity machines, solves this problem in an elegant way!</p> <p>Hadoop Operations and Cluster Management Cookbook is a practical and hands-on guide for designing and managing a Hadoop cluster. It will help you understand how Hadoop works and guide you through cluster management tasks.</p> <p>This book explains real-world, big data problems and the features of Hadoop that enables it to handle such problems. It breaks down the mystery of a Hadoop cluster and will guide you through a number of clear, practical recipes that will help you to manage a Hadoop cluster.</p> <p>We will start by installing and configuring a Hadoop cluster, while explaining hardware selection and networking considerations. We will also cover the topic of securing a Hadoop cluster with Kerberos, configuring cluster high availability and monitoring a cluster. And if you want to know how to build a Hadoop cluster on the Amazon EC2 cloud, then this is a book for you.</p>

Introduction


After finishing all the preparing tasks, we are ready to configure a Hadoop cluster in this chapter. First, we will give you some tips on choosing a proper Hadoop release version. Then we will show you how to configure a Hadoop cluster in pseudo-distributed and fully-distributed mode. Pseudo-distributed mode is a very good starting point if you have no experience configuring a Hadoop cluster. In this mode, we will configure all the Hadoop daemons to run on a single machine, which can give us the first feeling of a working Hadoop cluster while minimizing configuration difficulties. Next, we will show you how to validate a Hadoop cluster. The importance of validating a Hadoop cluster configuration will never be overemphasized. We typically use this step to confirm that the Hadoop cluster is running as expected. The last few recipes will show you how to install a few components in the cluster.
