> The hbck tool can not fix the six scenarios.
> 1. Version file does not exist in root dir.
>    Fix: I try to create a version file by 'FSUtils.setVersion' method.
>    
> 2. [REGIONNAME][KEY] on HDFS, but not listed in META or deployed on any region server.
>    Fix: I get region info form the hdfs file, this region info write to '.META.' table.
>    
> 3. [REGIONNAME][KEY] not in META, but deployed on [SERVERNAME]
>    Fix: I get region info form the hdfs file, this region info write to '.META.' table.
>    
> 4. [REGIONNAME] should not be deployed according to META, but is deployed on [SERVERNAME]
>    Fix: Close this region.
>    
> 5. First region should start with an empty key.  You need to  create a new region and
regioninfo in HDFS to plug the hole.
>    Fix: The region info is not in hdfs and .META., so it create a empty region for this
error.
> 6. There is a hole in the region chain between [KEY] and [KEY]. You need to create a
new regioninfo and region dir in hdfs to plug the hole.
>   Fix: The region info is not in hdfs and .META., so it create a empty region for this
hole.
