Jesus Camacho Rodriguez reassigned HIVE-19358:
----------------------------------------------
> 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
> Priority: Major
>
> 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.
