J-D,
I was able to run the 0.90.3 rc hbck on our hbase cluster and it does give more detail.
It gives more details. Two specific errors:
- ERROR: (regions <region1> and <region2>) Two regions have the same startkey:
- ERROR: (regions <region1> and <region2>) There is an overlap in the region
chain.
That is more detail, although I'm not really sure what to do with that information. Is there
a way to effectively repair from these two errors?
Thanks
Andy

Would you be able to patch in
https://issues.apache.org/jira/browse/HBASE-3695 and see what hbck
tells you now? Else you could try using the 0.90.3 rc0 which has it
too: http://people.apache.org/~stack/hbase-0.90.3-candidate-0/

It does seem like the table is in somewhat of a bad state ( e.g., there are two regions
that have blank start key but have different end keys ).

'hbase hbck -fix' and 'check_meta.rb -fix' and still have the above inconsistency so it looks
like I need to take manual action at this point but I'm a little stumped on how to go about
it.
