One must disagree with this. It doesn't matter what the technology is, if one has the appropriate mindset and enough years under the belt, it will be picked up.

What matters in terms of better value is whether or not one can understand the problems space and find an appropriate solution for it. All sorts of solution space solutions can be used, some of which are better than others. The point is to try and keep it simple enough for the user, irrespective of how difficult it might be for the IT guy.

The knowledge of Hadoop in and of itself is not as valuable as one would suggest it is.
