> 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).
> Note - there used to be an attachment with PDF, a write-up, it's now moved up to the
parent JIRA.
