I just got back from a little executive summit conference in Dallas for Chief Data Officers. Frustratingly, I heard a lot of folks telling me what Hadoop CAN’T do. Now, I know that Hadoop can’t bring about world peace or get my husband to put the toilet seat down, but the things people keep saying it can’t do are  things that I’ve personally DONE on Hadoop clusters, so I know they’re doable.

If you asked most people if water could cut through steel, they would probably tell you it can’t. They would be wrong, too.
