[jira] [Created] (HIVE-18573) Use proper Calcite operator instead of UDFs

slim bouguerra created HIVE-18573:
-------------------------------------

             Summary: Use proper Calcite operator instead of UDFs
                 Key: HIVE-18573
                 URL: https://issues.apache.org/jira/browse/HIVE-18573
             Project: Hive
          Issue Type: Bug
          Components: Hive
            Reporter: slim bouguerra


Currently, Hive is mostly using user-defined black box sql operators during Query planning. It will be more beneficial to use proper calcite operators.

Also, Use a single name for Extract operator instead of a different name for every Unit,  

Same for Floor function. This will allow unifying the treatment per operator.
