----------------------------------------------
Summary: CBO decorrelation logic should generate Hive operators
Key: HIVE-19358
URL: https://issues.apache.org/jira/browse/HIVE-19358
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 3.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Decorrelation logic may generate logical instances of the operators in the plan
(e.g., LogicalFilter instead of HiveFilter). This leads to errors while costing
the tree in the Volcano planner (used in MV rewriting), since logical operators
do not have a cost associated to them.
