Adam Kramer created HIVE-3491:
---------------------------------

             Summary: Expose column names to UDFs
                 Key: HIVE-3491
                 URL: https://issues.apache.org/jira/browse/HIVE-3491
             Project: Hive
          Issue Type: New Feature
          Components: Query Processor, UDF
            Reporter: Adam Kramer


If I run

SELECT MY_FUNC(a.foo, b.bar) FROM baz1 a JOIN baz2 b;

...the parsed query structure (i.e., that "foo" and "bar" are the name of the columns) should
be available to the UDF in some manner.
