Description: 
Currently, Hive is mostly using user-defined black box sql operators during 
Query planning. It will be more beneficial to use proper calcite operators, 
this is to prepare the ground for pushing complex expressions to Druid-calcite 
adapter.

 

 

  was:
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.
