--------------------------
Summary: Skip child tasks if parent task failed [Spark Branch]
Key: HIVE-9046
URL: https://issues.apache.org/jira/browse/HIVE-9046
Project: Hive
Issue Type: Improvement
Components: Spark
Affects Versions: spark-branch
Reporter: Chao
Currently, sometimes if a parent task failed, its child task(s) will continue
to execute, even the eventual result will be incorrect. This is demonstrated in
HIVE-8981.
It's a waste of time to continue in this case. We should detect such failures
and abandon the child tasks.
