Terrible review - claims "map reduce is dead" etc without any good reason as to why. Claims hive is a terrible idea because "it takes a long time to do a simple query on a 20MB dataset". Of course it does! Hive is meant to make it possible to work with gigantic datasets, not make it fast to work with a tiny 20MB dataset!
Shouldn't have made the HN frontpage - must be a light day.
