Subject [jira] Commented: (HBASE-2700) Handle master failover for regions in transition
Date Thu, 24 Jun 2010 18:50:49 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12882280#action_12882280
] 

Jonathan Gray commented on HBASE-2700:
--------------------------------------

@Todd, just bringing up that it's "possibly" untenable.  I don't think we need to make this
decision now and I'm not for or against it at this point.  In case of doing failover in this
style, you may have to hold 2X the assignment data (what meta says, and what each rs says).

> To this point in HBASE-2692 tasks we have moved everything for regions in transition
into ZK, but we have not fully handled the master failover case.  This is to deal with that
and to write tests for it.
