I'm kind of late to this map-reduce party in terms of large scale data processing. What is the paradigm shifting towards. The point about MR being a trivial subset seems rather obvious to me. Hadoop for instance is still in a phase of getting a lot of adoption yet is being implied as being a dead man walking. Raises a lot of very interesting postivie questions for me
