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>

Benchmarking a Hadoop cluster with GridMix


GridMix is a tool for benchmarking Hadoop clusters. It generates a number of synthetic MapReduce jobs and builds a model based on the performance of these jobs. Resource profiles of the cluster are modeled based on the job execution metrics. The profiles can help us find performance bottlenecks of the cluster. In this section, we will outline steps for benchmarking Hadoop with GridMix.

Getting ready

We assume that our Hadoop cluster has been properly configured and all the daemons are running without any issues.

Note

Currently, GridMix has three versions. For the purpose of differentiation and notation, we will use GridMix to represent GridMix version 1, use GridMix2 to represent GridMix version 2, and use GridMix3 to represent GridMix version 3.

Log in to the Hadoop cluster node from the administrator machine using the following command:

ssh hduser@master

How to do it...

Use the following steps to get GridMix2 benchmarks:

  1. Change the current working...
