---------------------------------
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.
