[jira] [Commented] (HBASE-10866) Decouple HLogSplitterHandler from
ZooKeeper
[ https://issues.apache.org/jira/browse/HBASE-10866?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13951541#comment-13951541 ]
Konstantin Boudnik commented on HBASE-10866:
--------------------------------------------
Thanks for the initial feedback, Stack! I think the main reason for doing this separation one handler at a time and just on the RS side is to limit the scope of the patches and make them easier to be digested. Would you suggest otherwise?

> 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).
