A sketch. Hadoop -> Cascalog -> Clojure atom -> Websocket -> ClojureScript Atom -> D3 -> Your eyes. Buzzword-tastic, but also kind of cool. Edit a query and watch the results unfold graphically before you. That's the idea. This is a prototype.
You want to try it out? Wow. Okay, you'll need to:
$ lein cljsbuild once # Build the Javascript
$ lein server # Run a websocket server.
$ cd resources/public ; python -m SimpleHTTPServer # Run a web server.
...and then pray.
