Xiangrui Meng created SPARK-4209:
------------------------------------
Summary: Support UDT in UDF
Key: SPARK-4209
URL: https://issues.apache.org/jira/browse/SPARK-4209
Project: Spark
Issue Type: New Feature
Components: SQL
Reporter: Xiangrui Meng
UDF doesn't recognize functions defined with UDTs. Before execution, an SQL
internal datum should be converted to Scala types, and after execution, the
result should be converted back to internal format (maybe this part is already
done).
