Someone please tell me what Hadoop, PIG, HIVE, Cascalog, et al. are doing that is fundamentally new? Reinventing the unix FILE, unix pipes, lisp, awk, sed, grep in a new "distributed bash shell"? I don't think this stuff, while brilliant and clever and useful, qualifies for a MacArthur grant when one is standing on the shoulders of N CS giants reimplementing their ideas with few truly novel improvements. MaCarthy, Kernigan, Thompson, Richie, McIlroy etc are those giants.
