Misleading title at best as Hadoop is a framework for the management and execution of map/reduce while the article demonstrates a map/reduce operation in R. I guess Hadoop has been ported to Clojure as well since I can just say:
(apply + (range 10))
And get an answer of 45. Hadoop must have been ported to MySQL as well:
SELECT type, SUM(price) FROM products GROUP BY type
It's not that I mind people pointing out the obvious (map/reduce style constructs have been around forever), but I'm accustomed to a port meaning something being migrated from one platform to another with a comparable feature set.
