> Key: HIVE-16964
> URL: https://issues.apache.org/jira/browse/HIVE-16964
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 1.0.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Priority: Major
>
> OrcRecordUpdater creates OrcRecordUpdater.ACID_FORMAT in the dir that it
> creates - but there is nothing Hive.moveAcidFiles() that copies it final
> location.
> It doesn't look like CompactorMR even attempts to create it.
