----------------------------------
Summary: Offline Meta Repair no longer points to the correct
location
Key: HBASE-8042
URL: https://issues.apache.org/jira/browse/HBASE-8042
Project: HBase
Issue Type: Bug
Components: documentation
Reporter: Kevin Odell
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.
$ ./bin/hbase org.apache.hadoop.hbase.util.OfflineMetaRepair
The path should be org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair
