Subject [jira] [Resolved] (HBASE-3742) Master receives unexpected region close but doesn't do anything
Date Tue, 13 Sep 2011 16:59:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3742?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jean-Daniel Cryans resolved HBASE-3742.
---------------------------------------

    Resolution: Won't Fix

Resolving as won't fix, lots of rework done for the master in trunk. If there's still an issue,
it'll probably come up differently.

> We got this in the context of HBASE-3741, a region was closed by a region server but
the master wasn't expecting it and didn't do anything about it. We had to force assign it
back.
