Is it really true that Hadoop > MapReduce? I was under the impression (as a limited outsider) that Hadoop is still trying to catch up to MapReduce.

Also, I've heard from a Google friend that MapReduce is no longer the production-level thing they use for large-scale calculations, but rather that Pregel has replaced it. (He said MapReduce is more analogous to what you use when you want a quick and dirty one-off command-line job.) Again, secondhand knowledge, though.
