> As some sort of follow-up or initial step towards HBASE-10296...
> Whatever consensus algorithm/library may be the chosen, perhaps on of first practical steps towards this goal would be to better abstract ZK-related API and details, which are now throughout the codebase (mostly leaked throuth ZkUtil, ZooKeeperWatcher and listeners).
> I'd like to propose a series of patches to help better abstract out zookeeper (and then help develop consensus APIs). 
> Here is first version of  patch for initial review (then I'm planning to work on another handlers in regionserver, and then perhaps start working on abstracting listeners).
