[jira] [Commented] (HBASE-25902) 1.x to 2.3.x upgrade does not work; you must install an hbase2 that is earlier than hbase-2.3.0 first

> 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
