Best Practices for Setting up and Maintaining Reliable Hadoop Clusters

Best Practices for Setting Up and Maintaining Hadoop Clusters

Storage and Analysis at Internet Scale

This book explains how to set up Hadoop to run on a cluster of machines. Running HDFS, MapReduce, and YARN on a single machine is great for learning about these systems, but to do useful work, they need to run on multiple nodes.

There are a few options when it comes to getting a Hadoop cluster, from building your own, to running on rented hardware or using an offering that provides Hadoop as a hosted service in the cloud. The number of hosted options is too large to list here, but even if you choose to build a Hadoop cluster yourself, there are still a number of installation options.

This chapter gives you enough information to set up and operate your own basic cluster, but even if you are using Hadoop cluster management tools or a service in which a lot of the routine setup and maintenance are done for you, these chapters still offer valuable information about how Hadoop works from an operations point of view.
