Michael Stack created HBASE-25902:
-------------------------------------

             Summary: 1.x to 2.3.x upgrade does not work; you must install an 
hbase2 that is earlier than hbase-2.3.0 first
                 Key: HBASE-25902
                 URL: https://issues.apache.org/jira/browse/HBASE-25902
             Project: HBase
          Issue Type: Bug
            Reporter: Michael Stack


Making note of this issue in case others run into it. At my place of employ, we 
tried to upgrade a cluster that was an hbase-1.2.x version to an hbase-2.3.5 
but it failed because meta didn't have the 'table' column family.

Up to 2.3.0, hbase:meta was hardcoded. HBASE-12035 added the 'table' CF for 
hbase-2.0.0. HBASE-23782 (2.3.0) undid hardcoding of the hbase:meta schema; 
i.e. reading hbase:meta schema from the filesystem. The hbase:meta schema is 
only created on initial install. If an upgrade over existing data, the hbase-1 
hbase:meta will not be suitable for hbase-2.3.x context as it will be missing 
columnfamilies needed to run (HBASE-23055 made it so hbase:meta could be 
altered (2.3.0) but probably of no use since Master won't come up).

It would be a nice-to-have if a user could go from hbase1 to hbase.2.3.0 w/o 
having to first install an hbase2 that is earlier than 2.3.0 but needs to be 
demand before we would work on it; meantime, install an intermediate hbase2 
version before going to hbase-2.3.0+ if coming from hbase-1.x
