If you've been tasked with the job of maintaining large and complex Hadoop clusters, or are about to be, this book is a must. You'll learn the particulars of Hadoop operations, from planning, installing, and configuring the system to providing ongoing maintenance. Hadoop is being adopted by more and more Fortune 500 companies, and the demand for operations-specific material has skyrocketed. This book - written by Eric Sammer, Principal Solution Architect at Cloudera - is the definitive operations guide for administrators. Developers who want to improve MapReduce jobs by learning how Hadoop works in large production environments will also benefit. Application administrators responsible for the health and operation of large distributed applications or systems will find this guide extremely useful.
