Raspberry Pi Super Cluster

By: Andrew K. Dennis

Overview of this book

A cluster is a type of parallel/distributed processing system which consists of a collection of interconnected stand-alone computers cooperatively working together. Using Raspberry Pi computers, you can build a two-node parallel computing cluster which enhances performance and availability. This practical, example-oriented guide will teach you how to set up the hardware and operating systems of multiple Raspberry Pi computers to create your own cluster. It will then navigate you through how to install the necessary software to write your own programs such as Hadoop and MPICH before moving on to cover topics such as MapReduce. Throughout this book, you will explore the technology with the help of practical examples and tutorials to help you learn quickly and efficiently. Starting from a pile of hardware, with this book, you will be guided through exciting tutorials that will help you turn your hardware into your own super-computing cluster. You'll start out by learning how to set up your Raspberry Pi cluster's hardware. Following this, you will be taken through how to install the operating system, and you will also be given a taste of what parallel computing is about. With your Raspberry Pi cluster successfully set up, you will then install software such as MPI and Hadoop. Having reviewed some examples and written some programs that explore these two technologies, you will then wrap up with some fun ancillary projects. Finally, you will be provided with useful links to help take your projects to the next step.

Installing Java

Java, as you may know, is an OOP language that has its syntactical roots in the C and C++ programming languages. It is also the language we will be using to interact with the Hadoop framework.

We will start by installing Java onto our Master Raspberry Pi. Make sure you have logged into this machine.

The latest version of the Java Development Kit (JDK) can be found on the Oracle website at the following URL:

You should note that some versions of Java (including hard-float versus soft-float) might not be compatible with your Raspberry Pi.

You can always refer to the RPi Java JDK installation guide for updates available at the following link:


Remember you can update your Raspberry Pi's package list by running apt-get update.

To start the Java installation, run the following command:

sudo apt-get install openjdk-7-jdk

You will now see the process running in...
