Subject [jira] [Updated] (HBASE-6417) hbck merges .META. regions if there's an old leftover
Date Wed, 18 Jul 2012 00:15:33 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6417?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

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.

> 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.
> I'll be attaching the full log in a separate file.
