Mikhail Antonov commented on HBASE-10866:
-----------------------------------------
Another usecase for ZK worth mentioning is ephemeral znodes operation, for live
RSs tracking, for example. Learning about such event is as described in usecase
3, but sending such notification would be little different.
> Decouple HLogSplitterHandler from ZooKeeper

> Project: HBase
> Issue Type: Improvement
> Components: regionserver, Zookeeper

> 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).
