-----------------------------------
> CTAS query failure at DDL task stage doesn't clean out the target directory
> ---------------------------------------------------------------------------
>
> Key: HIVE-22452
> URL: https://issues.apache.org/jira/browse/HIVE-22452
> Project: Hive
> Issue Type: Bug
> Components: Hive
> Affects Versions: 3.1.2, 3.1.0
> Reporter: Riju Trivedi
> Assignee: Riju Trivedi
> Priority: Major
>
> CTAS query failure at DDL task stage due to HMS connection issue leaves the
> output file in target directory. Since DDL task stage happens after Tez DAG
> completion and MOVE Task , output file gets already moved to target
> directory and does not get cleaned up after the query failure.
> Re-executing the same query causes a duplicate file under table location
> hence duplicate data.
