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>

Creating the kickstart file and boot media


Installing Linux on a large number of nodes with a kickstart file has a few advantages. For example, the installation process can be automated by specifying a list of to-be installed packages and configuring system settings for the post-installation process.

In this section, we will cover steps of creating a kickstart file and a USB boot media with the operating system image.

Getting ready

A kickstart file is a plain text file used for the automatic installation of Linux.

  1. Prepare a USB flash drive with storage capacity larger than 512MB. The drive should have a single vfat filesystem partition. We can use the following command to check the filesystem type:

    blkid
    

    Note

    We should see a message similar to the following:

    /dev/sdb1 SEC_TYPE="msdos" LABEL="LIVE" UUID="07D9-051C" TYPE="vfat"

  2. If the TYPE attribute is other than vfat, use the following command to clear the first few blocks of the drive:

    dd if=/dev/zero of=/dev/sdb1 bs=1M count=100
    
  3. Log in to the...
