----------------------------------
Summary: FileSinkOperator should delete existing output target
when renaming
Key: HIVE-16156
URL: https://issues.apache.org/jira/browse/HIVE-16156
Project: Hive
Issue Type: Bug
Components: Operators
Affects Versions: 1.1.0
Reporter: Xuefu Zhang
Assignee: Xuefu Zhang
If a task get killed (for whatever a reason) after it completes the renaming
the temp output to final output during commit, subsequent task attempts will
fail when renaming because of the existence of the target output. This can
happen, however rarely.
Hive should check the existence of the target output and delete it before
renaming.
