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>

Preparing a local machine for EC2 connection


A local client machine is required for accessing EC2. For example, we can use the local client machine to launch EC2 instances, log in to the instances on EC2, and so on. In this recipe we will list steps to configure a local machine for EC2 connection.

Getting ready

Before getting started, we assume that we have registered with AWS and security credentials have been created. We also assume that a machine with Linux has been installed.

How to do it...

Use the following steps to configure a local machine for EC2 remote access:

  1. Get the Access Key ID and the Secret Access Key from the security credentials web page as shown in the following screenshot:

  2. Move the key pair to the .ec2 directory using the following command:

    mv <key-pair-name>.pem ~/.ec2/
    
  3. Move the private key file to the .ec2 directory using the following command:

    mv pk-*.pem ~/.ec2/
    
  4. Move the certificate file to the .ec2 directory using the following command:

    mv cert-*.pem ~/.ec2/
