Done now. I modified slightly terminology around coordination engine and commented on one of Ted's questions.

>             Project: HBase
>          Issue Type: Umbrella
>          Components: Consensus, Zookeeper

> As some sort of follow-up or initial step towards HBASE-10296.
> Whatever consensus algorithm/library may be the chosen, perhaps one 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).
> This jira is umbrella for relevant subtasks.
> As the design doc is in process of peer-review now, please use Google Doc (linked below) instead of pdf.
