Abhay updated HIVE-26438:
-------------------------
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.
