             Summary: Retrying task could use cached bad operators [Spark Branch]
                 Key: HIVE-9993
                 URL: https://issues.apache.org/jira/browse/HIVE-9993
             Project: Hive
          Issue Type: Bug
    Affects Versions: spark-branch
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang
             Fix For: spark-branch


For a Spark task, it could be retried on the same executor in case some failures. In retrying, the cache task could be used. Since the operators in the task are already initialized, they won't be initialized again. The partial data in these operators could lead to wrong final results.
