             Summary: Acid V1 to V2 upgrade
                 Key: HIVE-19598
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0
            Reporter: Eugene Koifman
            Assignee: Eugene Koifman

The on-disk layout for full acid (transactional) tables has changed 3.0.

Any transactional table that has any update/delete events in any deltas that 
have not been Major compacted, must go through a Major compaction before 
upgrading to 3.0.  No more update/delete/merge should be run after/during major 

Not doing so will result in data corruption/loss.


Need to create a utility tool to help with this process.  HIVE-19233 started 
this but it needs more work.
