-------------------------------------
Summary: AcidUtils.Directory.getAbortedDirectories() may be missed
for full CRUD tables
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
{{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.
