Typically, it runs on big clusters of computers working together to crunch large
chunks of data. You also can run Hadoop in "single-cluster mode" on a
Linux machine, Windows PC or Mac, to learn the technology or do testing and
debugging. The Hadoop framework, however, is not quickly mastered. Apache's
Hadoop wiki cautions: "If you do not know about classpaths,
how to compile and debug Java code, step back from Hadoop and learn a bit more about Java before
proceeding." But if you are reasonably comfortable with Java, the well-written
Hadoop Beginner's Guide by Garry Turkington can help you start mastering this
rising star in the Big Data constellation."
