The thing about Hadoop, per se, is that it’s not a packaged solution by any means. Rather, it’s a complex collection of modules that enable high-quality programmers to leverage massive parallel processing algorithms to do very specific things. But there’s no fancy user interface, and the manuals are brutal.
Add to that challenge this critical hurdle: you also need business people who have at least a general understanding of what it can do. Those folks must be able to conjure up ideas of how it can be used, then communicate to the developers, who must subsequently produce, test, implement and support applications.
