Description

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.
