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 Pig


Similar to Hive, Pig provides a handy tool for manipulating Hadoop data. In this recipe, we are going to discuss the installation of Apache Pig.

Getting ready

Before we install Pig, we need to make sure Hadoop has been properly installed. Please refer to the previous sections about the configuration of a Hadoop cluster.

Download the Pig archive file from a mirror site with the following command on the administrator machine:

wget http://www.motorlogy.com/apache/pig/stable/pig-0.10.1.tar.gz ~/repo

How to do it...

Use the following steps to configure Pig:

  1. Log in to the master node from the Hadoop administrator machine as hduser with the following command:

    ssh hduser@master
    
  2. Copy the archive to /usr/local with the following command:

    sudo wget ftp://hadoop.admin/repo/pig-0.10.1.tar.gz /usr/local
    
  3. Decompress the Pig archive file with the following command:

    cd /usr/local
    sudo tar xvf pig-0.10.1.tar.gz
    
  4. Create a symbolic link to the Pig directory using the following command:

    sudo ln -s /usr...
