> B.4.3. Special case: Root and META are corrupt.
> The most drastic corruption scenario is the case where the ROOT or META is corrupted
and HBase will not start. In this case you can use the OfflineMetaRepair tool create new ROOT
and META regions and tables. This tool assumes that HBase is offline. It then marches through
the existing HBase home directory, loads as much information from region metadata files (.regioninfo
files) as possible from the file system. If the region metadata has proper table integrity,
it sidelines the original root and meta table directories, and builds new ones with pointers
to the region directories and their data.

> The path should be org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair
