Date Tue, 16 Nov 2010 17:08:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-3235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gary Helmling updated HBASE-3235:
---------------------------------

         Priority: Blocker  (was: Major)
    Fix Version/s: 0.90.0

Bumping up as a blocker and marking for 0.90.0 since it represents possible data loss.
