Advantages of Hadoop

Hadoop offers many advantages for your company or business:  "Large scale QA efforts, do not need to find new hardware to experiment, projects move from research to production easily, easy to learn, 'even our rocket scientists use it', the clusters just work, research questions answered in days not in months, [more important] you can work with all your data! "

- Eric Baldeschwieler
