• Easy-to-follow administrator’s guide with step-by-step explanations to help you master Apache Hadoop

In Detail

Apache Hadoop is an open source distributed computing technology that assists users in processing large volumes of data with relative ease, helping them to generate tremendous insights into their data. Cloudera, with their open source distribution of Hadoop, has made data analytics on big data possible and accessible to anyone interested.

This book fully prepares you to be a Hadoop administrator, with special emphasis on Cloudera’s CDH. It provides step-by-step instructions on setting up and managing a robust Hadoop cluster running CDH5. This book will also equip you with an understanding of tools such as Cloudera Manager, which is currently being used by many companies to manage Hadoop clusters with hundreds of nodes. You will learn how to set up security using Kerberos. You will also use Cloudera Manager to set up alerts and events that will help you monitor and troubleshoot cluster issues.
