-----------------------------------
Summary: Make dynamic sort partition optimization available to HoS
and MR
Key: HIVE-20915
URL: https://issues.apache.org/jira/browse/HIVE-20915
Project: Hive
Issue Type: Bug
Components: Query Planning
Affects Versions: 4.0.0
Reporter: Yongzhi Chen
Assignee: Yongzhi Chen
HIVE-20703 put dynamic sort partition optimization under cost based decision,
but it also makes the optimizer only available to tez.
hive.optimize.sort.dynamic.partition works with other execution engines for a
long time, we should keep the optimizer available to them.
