----------------------------
Summary: SHUFFLE_SORT should only be used for order by query
[Spark Branch]
Key: HIVE-9561
URL: https://issues.apache.org/jira/browse/HIVE-9561
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Rui Li
Assignee: Rui Li
The {{sortByKey}} shuffle launches probe jobs. Such jobs can hurt performance
and are difficult to control. So we should limit the use of {{sortByKey}} to
order by query only.
