Date Wed, 24 Feb 2016 15:03:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15318?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15163149#comment-15163149

stack commented on HBASE-15318:

[~java8964] State will be kept in master with final end assignment published to master. Say
what is missing and we'll try and fill it into the design.  It is unfinished IIRC. [~syuanjiang]
and [~mbertozzi] FYI.

> Current region server state is managed via znode created by region server, master just
listen these nodes. but we find many user network issue is not network disconnected but package
lost, which is hard to capture because connection between region server and zk is fine.
> This jira goal is region server state is managed by master without shared info in zk,
via enhancement heartbeat from region server to master.
