Takeshi Yamamuro updated SPARK-6912:
------------------------------------
Environment: (was: 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;
https://github.com/kyluka/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/udf/generic/GenericUDFBridge.java#L163
https://github.com/l1x/apache-hive/blob/master/hive-0.8.1/src/serde/src/java/org/apache/hadoop/hive/serde2/objectinspector/ObjectInspectorFactory.java#L118
