What you need for this book?

The following software suites are required to try out the examples in the book:

Java Development Kit (JDK 1.7 or later): This is free software from Oracle that provides a JRE (Java Runtime Environment) and additional tools for developers. It can be downloaded from http://www.oracle.com/technetwork/java/javase/downloads/index.html.
The IDE for editing Java code: IntelliJ IDEA is the IDE that has been used to develop the examples. Any other IDE of your choice can also be used. The community edition of the IntelliJ IDE can be downloaded from https://www.jetbrains.com/idea/download/.

Maven: Maven is a build tool that has been used to build the samples in the book. Maven can be used to automatically pull-build dependencies and specify configurations via XML files. The code samples in the chapters can be built into a JAR using two simple Maven commands:

mvn compile
mvn assembly:single

These commands compile the code into a JAR file. These commands create a consolidated JAR with the program along with all its dependencies. It is important to change the mainClass references in the pom . xml to the driver class name when building the consolidated JAR file.

Hadoop-related consolidated JAR files can be run using the command:

hadoop jar <jar file> args

This command directly picks the driver program from the mainClass that was specified in the pom . xml. Maven can be downloaded and installed from http://maven.apache.org/download.cgi. The Maven XML template file used to build the samples in this book is as follows:

Hadoop 2.2.0: Apache Hadoop is required to try out the examples in general. Appendix, Hadoop for Microsoft Windows, has the details on Hadoop's single-node installation on a Microsoft Windows machine. The steps are similar and easier for other operating systems such as Linux or Mac, and they can be found at http://hadoop.apache.org/docs/r2.2.0/hadoop-project-dist/hadoop-common/SingleNodeSetup.html
