additional columns even in the absence of order by

Prasanth J updated HIVE-8162:
-----------------------------
Summary: Dynamic sort optimization propagates additional columns even in the absence of order by (was: hive.optimize.sort.dynamic.partition causes RuntimeException for inserting into dynamic partitioned table when map function is used in the subquery )

> The query worked fine in Hive-0.12 and Hive-0.13. It starts failing in Hive-0.13. If hive.optimize.sort.dynamic.partition is turned off in Hive-0.13, the exception is gone.
