Subject [jira] Created: (HBASE-905) Remove V5 migration classes from 0.19.0
Date Fri, 26 Sep 2008 19:17:44 GMT
Remove V5 migration classes from 0.19.0

                 Key: HBASE-905
                 URL: https://issues.apache.org/jira/browse/HBASE-905
             Project: Hadoop HBase
          Issue Type: Task
          Components: util
            Reporter: Jim Kellerman
            Assignee: Jim Kellerman
             Fix For: 0.19.0

The V5 migration package was needed to migrate from hbase-0.1.x to hbase-0.2.x (and also can
migrate from 0.1 to 0.18.x)

As migration is very complex, if a migration is needed to 0.19 or a future release, removing
these classes and modifying the migration too to not require them will simplify future migrations.

A note will be placed on the Wiki notifying users that if they need to migrate from 0.1 to
0.19 (or greater), they must first install 0.2.x or 0.18.x, run the migration, and then install
the new version to migrate to it.
