Re: Table listed in "list", but not in .META.

Hi Marco,

      There seems to be some problem with the regionserver hosting the
table. Had you disabled or deleted "foo"?And try to see what "hbck"
says. And RegionAlreadyInTransitionException: is normally thrown if a
region server is asked to open or close a region but it's already
processing that region. BTW, did you find anything abnormal with your
HDFS??
Regards,
    Mohammad Tariq
