Subject [jira] [Updated] (HBASE-10909) Abstract out ZooKeeper usage in HBase
Date Tue, 13 May 2014 01:17:21 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10909?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mikhail Antonov updated HBASE-10909:
------------------------------------

    Description: 
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. Design doc is attached, for comments/questions
there's a google doc linked.
