I'm obviously the wrong person to talk about Hadoop - having so little experience with it - but this article strikes me as link bait. To answer your question, the author seems to think if you have Hadoop, you'll never need NoSQL. Here's his quote: "I think we're going to see Hadoop produce the next Oracle-sized database company. We're also likely to see such a company emerge from the NoSQL ranks, but Hadoop is a near certain bet right now." This quote also seems wrong to me: "In fact, if anything, we are still only on the first few steps of the Big Data marathon, a race that Hadoop seems set to win despite its many shortcomings." I believe the Big Data industry is well on its way. There are multiple big players offering an array of cloud services and software.
