That's what I'm wondering about. It seems to me that hbck currently is
overly aggressive fixing things (see also HBASE-6417 where it merged
.META.). So should we have all the heuristics to detect problems and
then add the corner cases after as people find them? Or should we let
the users decide what should be fixed? It could be that we should ask
more questions to the users. I'm thinking out loud here.
