Subject RE: wrong region exception
Date Thu, 26 May 2011 15:06:19 GMT
It looks like an entire region is missing, here is the online table:

urlhashv2,7FF1A5BF839C37078083B4F8267008F6,1303028235302.b0d55566fd0e02ae98541618396aa7b1.
 	 c1-s03.atxd.maxpointinteractive.com:60030   	7FF1A5BF839C37078083B4F8267008F6  	80116D7E506D87ED39EAFFE784B5B590
urlhashv2,8031483E0B3B7F587020FCBB764272D9,1305226123483.3ed065ad87f89aece6b994dd31b42b2a.
	c1-s33.atxd.maxpointinteractive.com:60030 	8031483E0B3B7F587020FCBB764272D9 	8041346D0B05617FA4B9152BFE9B18B9

One ends at 80116D7E506D87ED39EAFFE784B5B590, but the next one doesn't start there.

How do I fix this?

That region is not in the urlhashv2 directory.

I'll grep all the logs to see if it shows up.

Can you find this region in the filesystem?  Look under the urlhashv2 table directory for
a direction named 80116D7E506D87ED39EAFFE784B5B590.  Grep your master log to see if you can
figure the history of this region.

 See if adding -fix to hbck will clean up your prob.

 If 0.90.x, try running ./bin/hbase hbck.  See what it says.
