[jira] [Created] (HIVE-5025) Column aliases for input argument of GenericUDFs

Navis created HIVE-5025:
---------------------------

             Summary: Column aliases for input argument of GenericUDFs 
                 Key: HIVE-5025
                 URL: https://issues.apache.org/jira/browse/HIVE-5025
             Project: Hive
          Issue Type: Improvement
          Components: UDF
            Reporter: Navis
            Assignee: Navis
            Priority: Trivial


In some cases, column aliases for input argument are very useful to know. But I cannot sure of this in the sense that UDFs should not be dependent to contextual information like column alias.
