> The plugin registry connects configurations, stored in ZK, with implementations, which are Java classes. The registry handles a large number of tasks including:
> * Populating "bootstrap" plugin configurations and handling upgrades.
> * Reading from, and writing to, the persistent store in ZK.
> * Handling "normal" (configured) plugins and special system plugins (which have no configuration.)
> * Handle format plugins which are always associated with the DFS storage plugin.
> * And so on.
> The code has grown overly complex. As we look to add a new, cleaner plugin mechanism, we will start by cleaning up what we have to allow the new mechanism to be one of many.
