The following page has been changed by stack: http://wiki.apache.org/hadoop/Hbase/Migration ------------------------------------------------------------------------------ * The migration script is named o.a.h.hbase.util.Migrate. Run it by invoking '''${HBASE_HOME}/bin/hbase migrate'''. * 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. + * This latter may be necessary when types change radically -- so much so that version D cannot interpret version A or B types.
