Free MapReduce and Hadoop lectures from UC Berkeley. Good launching point for exploring Hadoop.

I’ve been watching two lectures from UC Berkeley’s CS61A course, on MapReduce in general and (in the second lecture) Hadoop specifically. If you’re looking for a good, deep kick-starter on both the concepts and the implementation, I’d recommend them. They’re a little dry (hey, they are university CS lectures), and you’ll need to focus on them as they move relatively quickly, but they reward the concentration with, I think, a really good launching point for playing with Hadoop. The lectures are up on YouTube here and here, but note there is a download link so you can watch them offline.
