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>

Installing the Linux operating system


Although there are many ways to install Linux on a machine, installing over the network with the help of a kickstart file is the most efficient option. The installation process can be automated requiring minimal human intervention. A kickstart file can be kept on a server and read by individual machines during the installation process. In the recipe, we will outline steps to install Linux on a number of Hadoop nodes over the network.

Getting ready

Before getting started, we need to verify that the DHCP server and FTP server are running correctly on the administrative machine.

Use the following command on the administrator machine to check if the DHCP server is working properly:

ps -ef | grep dhcp

If this command gives non-empty output, then it is working correctly, otherwise, we need to start the service with the following command:

sudo service dhcpd start

Similarly, the following command can be used to check the FTP server on the administrator machine...
