[jira] [Created] (HIVE-8501) Fix CBO to use indexes when GenericUDFBridge is applied

Pengcheng Xiong created HIVE-8501:
-------------------------------------

             Summary: Fix CBO to use indexes when GenericUDFBridge is applied 
                 Key: HIVE-8501
                 URL: https://issues.apache.org/jira/browse/HIVE-8501
             Project: Hive
          Issue Type: Improvement
            Reporter: Pengcheng Xiong
            Priority: Minor


previous https://issues.apache.org/jira/browse/HIVE-8389 assumes that
we have predicate: ((UDFToDouble(key) > UDFToDouble(80)) and (UDFToDouble(key) < UDFToDouble(100))) for example.
This does not work for the case when we have predicate: ((UDFToDouble(key) > 80.0) and (UDFToDouble(key) < 100.0))
