Takeshi Yamamuro updated SPARK-6912:
------------------------------------
Description:
The current implementation can't handle Map<K,V> as a return type in Hive UDF.
We assume an UDF below;
public class UDFToIntIntMap extends UDF {
public Map<Integer, Integer> evaluate(Object o);
}
Hive supports this type, and see a link below for details;
