      Description

      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.
