Priority: Critical (was: Major)
> Acid V1 to V2 upgrade
> ---------------------
>
> Key: HIVE-19598
> URL: https://issues.apache.org/jira/browse/HIVE-19598
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Priority: Critical
>
> 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.
