Xuefu Zhang commented on HIVE-9046:
-----------------------------------
I believe the root cause of this issue is that the task doesn't return failed
status (code) properly.
> 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: Bug
> 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.
