[jira] [Created] (HIVE-9649) Skip orderBy or sortBy for intermediate result [Spark Branch]

Xuefu Zhang created HIVE-9649:
---------------------------------

             Summary: Skip orderBy or sortBy for intermediate result [Spark Branch]
                 Key: HIVE-9649
                 URL: https://issues.apache.org/jira/browse/HIVE-9649
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Xuefu Zhang


orderBy and sortBy seem relevant only to the final result. Thus, for most of cases, if not all, orderBy/sortBy can be ignored for efficiency. This JIRA is to identify the opportunity and optimize it accordingly.
