> hbck does not handle the case where all the regions of a table is gone. To reproduce
this: 
> 1. create table with one region 
> 2. delete the region directory
> 3. run hbck --repair, which removes the region from meta as well 
> 4. now, the meta won't contain the region, but the table dir in hdfs will be there.
