[jira] [Created] (HIVE-9046) Skip child tasks if parent task failed [Spark Branch]

Chao created HIVE-9046:
--------------------------

             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.
