Description

It's hard to get designers and front end developers to iterate on our web ui, partly because it's not well separated, and partly because it's in java jsp/jamon. It would be awesome to have something like Accumulo's monitor.

Have all of the current daemons just publish everything through json and remove the current UI. Then we can separate the ui out into a monitor daemon that's just UI.

This would do a couple of things:

• force us to publish everything that's interesting though the
  metrics system. (Lots of stuff is there but some stuff isn't there.)
• remove a lot of resources from our hbase-server jar.
• make it easier to add graphing other features to the ui.
• allow us to remove some things from the rs -> master heart beat.
• encourage front end developers to get involved (wishful ?)
