Hadoop is a software framework designed for use with Apache, which is first and foremost a Linux server application. Yet there are development versions of Hadoop available for Windows and Mac as well. These are what are called single node instances, that is they use a single computer to simulate the existence of a large cluster of computers. See if you can install the appropriate version of Hadoop for your computer’s operating system.
As a bonus activity, if you are successful in installing Hadoop, then get a copy of the RHadoop package from RevolutionAnalytics and install that. If you are successful with both, you should be able to run the MapReduce code presented in this chapter.
