Any transactional tables created by a Hive version prior to Hive 3 require Major Compaction to be run on every partition before upgrading to 3.0. More precisely, any partition which has had any update/delete/merge statements executed on it since the last Major Compaction, has to undergo another Major Compaction. No more update/delete/merge may happen on this partition until after Hive is upgraded to Hive 3. |
