----------------------------------------------
Summary: Extend HiveSortLimitPullUpConstantsRule to pull up
constants even when SortLimit is the root of the plan
Key: HIVE-13805
URL: https://issues.apache.org/jira/browse/HIVE-13805
Project: Hive
Issue Type: Sub-task
Components: CBO
Affects Versions: 2.1.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Follow-up of HIVE-13068.
Limitation in the original HiveSortLimitPullUpConstantsRule rule.
Currently Calcite rule does not pull-up constants when the Sort/Limit operator
is on top of the operator tree, as this was causing Hive limit related
optimizations to not kick in.
