Subject [Hadoop Wiki] Trivial Update of "Hbase/Migration" by stack
Date Mon, 14 Jul 2008 22:16:52 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The following page has been changed by stack:
http://wiki.apache.org/hadoop/Hbase/Migration

------------------------------------------------------------------------------
   * Versions are explicit integers.  The first version is '''1'''.
   * The version of a particular '''hbase.rootdir''' install is recorded into a file at the
top-level named '''hbase.version'''.
   * Its OK if a migration that spans versions A-D requires that you first install version
C, migrate from A-C, then install D and finish the migration from C-D.
-   * In particular, to migrate a 0.16.x hbase to 0.2, you must first install hbase 0.1, run
the migration from 0.16.x to 0.1 and then install 0.2 to migration from 0.1 to 0.2.
