We need to update add_table.rb at least. The onlining of regions was done by the metascan. It no longer exists in 0.90. Maybe a disable/enable after an add_table.rb would do but probably better to revamp and merge it with hbck? > Results from torture tests that HBase was subjected to in the timeframe > leading up to 0.90 also resulted in better handling of .META. table related > errors.

I was hoping Wayne had a snapshot of .META. to help at least characterize the problem. (This does sound like something our Dan Harvey ran into recently on an hbase 0.20.x hbase. Let me go back to him. He might have some input that will help here.) St.Ack
