[jira] [Created] (HIVE-9744) Move common arguments validation and value extraction code to GenericUDF

Alexander Pivovarov created HIVE-9744:
-----------------------------------------

             Summary: Move common arguments validation and value extraction code to GenericUDF
                 Key: HIVE-9744
                 URL: https://issues.apache.org/jira/browse/HIVE-9744
             Project: Hive
          Issue Type: Improvement
          Components: UDF
            Reporter: Alexander Pivovarov
            Assignee: Alexander Pivovarov
            Priority: Minor


most of the UDFs 
- check if arguments are primitive / complex
- check if arguments are particular type or type_group
- get converters to read values
- check if argument is constant
- extract arguments values

Probably we should move these common methods to GenericUDF
