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; 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 > Support Map<K,V> as a return type in Hive UDF > --------------------------------------------- > > Key: SPARK-6912 > URL: https://issues.apache.org/jira/browse/SPARK-6912 > Project: Spark > Issue Type: Bug > Components: SQL > Reporter: Takeshi Yamamuro > > The current implementation can't handle Map<K,V> as a return type in Hive > UDF.
