Subject Re: HBase exception after upgrading from hbase-0.90-branch to trunk
Date Tue, 16 Aug 2011 04:42:04 GMT
Oh, are you running on hbase trunk?  If so, did you write all your
data with TRUNK or did you start up 0.92 on a data that was written w/
0.90 (It should work but you may have hit an issue).
