---------------------------

             Summary: Add reflect UDF for member method invocation of column
                 Key: HIVE-4025
                 URL: https://issues.apache.org/jira/browse/HIVE-4025
             Project: Hive
          Issue Type: Improvement
          Components: UDF
            Reporter: Navis
            Assignee: Navis
            Priority: Trivial


There are many useful non-static methods on type of primitive types. But 
current reflect UDF cannot invoke those. For example,

select reflect2(value, "replace", "val", "VALUE") from src;

which replaces 'val' part of value column with 'VALUE'
