             Summary: Union all query finished with errors [Spark Branch]
                 Key: HIVE-7773
                 URL: https://issues.apache.org/jira/browse/HIVE-7773
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Rui Li
            Priority: Critical


When I run a union all query, I found the following error in spark log (the query finished with correct results though):

Judging from the log, I think we don't properly handle the input paths when cloning the job conf, so it may also affect other queries with multiple maps or reduces.
