Hi all,

1. After I run hbase hbck -fix, I got one region(for record table) says, this region is not deploy on any region server. But I can find the region entry in .META. table. but hbase region server complain on this region, Could anyone shed some light on this:

2012-11-01 23:59:59,930 ERROR org.apache.hadoop.hbase.regionserver.handler.OpenRegionHandler: Failed open of region=record,\x00com.boardreader.video.youtube.zqzOohI9R4c,1351688450154.d963e4aa86acdffd4bc1bf3f4688a4d4.

Hi Jun,

I don't remember exact syntax, but this .META. is indeed a folder in a Hadoop filesystem, and you should use "hadoop –fs rm xxxx" command to remove specific file from /.META./xxxx… I also think you can simply ignore this error message…

(please double-check syntax in test environment…)
