I checked the master, unfortunately , I must have wrong setting that all
master log are not there.
So I checked the regionserver which hosted this region. I have 14 days log
there and I grep this 02f9ec575b19864ae44e714d9245138f,
and I don't see any log. then I searched all regionserver's log for last
several days , and don't see
any log related to this region either.

Subject: Re: hbase hbck error
I don't remember seeing this sort of issue a lot, or at all... Usually
the region would not be on .META. so it looks like a different issue.
Could you grep the master logs and see what's the story of that
region? Just look for 02f9ec575b19864ae44e714d9245138f and try to
figure what happened to that region, might give us a clue.

Hi,
today I run "hbase hbck " to check our production cluster and dev
cluster,
the production cluster comes out clean, but
in our dev cluster, I have seem more than 2K errors like this:
ERROR: Region
HEARTBEAT_MASTERPATCH,time\x09daily\x092010-08-15\x09uobkayhian_pr
oduction\x09patch-0000694,1287356584131.02f9ec575b19864ae44e714d9245138f.
found
in META, but not in HDFS, and deployed on m0002040.ppops.net:60020
I checked hbase GUI, and indeed , it is correct, the region is loaded by
the
region server, but the hdfs directory
is not there.
I am running cdh3u0, and I wonder how this can happen. Once it has
happened,
what can I do to recover to bring the table back to healthy state.
Jimmy.
