Subject [jira] Updated: (HBASE-3376) NPE in RegionTransitionData.fromBytes
Date Wed, 22 Dec 2010 18:36:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-3376:
-------------------------

    Fix Version/s:     (was: 0.90.0)
                   0.90.1

Moved to 0.90.1.  I should have added history on this region from logs to this issue; w/o
it, it makes it hard to figure how we got to this condition.
