Hi there, It seems, that I had the same problem. AFAIK fix_table and hbck currently won't be able to fix this, so I wrote myself two small tools. A first one detects such loops in the meta table: https://gist.github.com/894031#file_h_base_region_loops.java If you specify '--fix', the loopy/duplicated regions are moved to a directory you specify and the meta is updated. The second one (https://gist.github.com/894031#file_add_records_from_region.java) takes one of a moved region as input and adds its content to the specified table, if there isn't already an entry with the same family:qualifier (this fitted my needs, as I only have one entry per family:qualifier). DISCLAIMER: Those tools were programmed rather quickly, so please make sure, that they serve your needs.
If you have fixed your table, I would migrate as quickly as possible to 0.90.x! Best, Lukas
