> 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 compaction.
> 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.
