> Remove unnecessary optimization in canHandleQbForCbo() method
> -------------------------------------------------------------

> Key: HIVE-26438

> This ticket is an improvement on
> https://issues.apache.org/jira/browse/HIVE-26426. The canHandleQbForCbo()
> checks whether Calcite handle the query or not and it returns null if the
> query can be handled; non-null reason string if it cannot be.
> But currently, it returns an empty string if INFO Log is not enabled. This is
> probably a performance optimization that is not needed and can be simplified.
