Jean-Daniel Cryans updated HBASE-6417:
--------------------------------------
Attachment: hbck.log
The full log on what happened. I was able to fix it by recreating the old
region's folder, moving the right store file back and moving a .regioninfo from
somewhere else. Good thing it was a dev cluster.
> hbck merges .META. regions if there's an old leftover

> Trying to see what caused HBASE-6310, one of the things I figured is that the
> bad .META. row is actually one from the time that we were permitting meta
> splitting and that folder had just been staying there for a while.
> So I tried to recreate the issue with -repair and it merged my good .META.
> region with the one that's 3 years old that also has the same start key. I
> ended up with a brand new .META. region!
> I'll be attaching the full log in a separate file.
