-----------------------------------
Summary: 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
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.
