> ------------------------------------------------------------------------------
>
> Key: HIVE-20460
> URL: https://issues.apache.org/jira/browse/HIVE-20460
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 3.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Priority: Major
>
> {{Directory.getAbortedDirectories()}} lists deltas where all txns in the range are aborted.
> These are then purged by {{Worker}} (\{{CompactorMR}} but only for insert-only tables.
> Full CRUD tables currently rely on {{FileSystem.rename()}} in {{MoveTask}} and so no reader (or {{Cleaner}} should every see a delta where all data is aborted.
>
> Once rename() is eliminated for full CRUD (just like insert-only) transactional tables, Cleaner (or Worker) should take care of these.
