Key: HIVE-3491
URL: https://issues.apache.org/jira/browse/HIVE-3491
Project: Hive
Issue Type: New Feature
Components: Query Processor, UDF

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.
