> I have a UDF with the following evaluate method :
> public Text evaluate(Text argument, Map<Text, Text> params)
> And when i tried invoking this UDF, i was getting the following error.
> scala.MatchError: interface java.util.Map (of class java.lang.Class)
> at org.apache.spark.sql.hive.HiveInspectors$class.javaClassToDataType(HiveInspectors.scala:35)
> at org.apache.spark.sql.hive.HiveFunctionRegistry.javaClassToDataType(hiveUdfs.scala:37)
> had a look at HiveInspectors.scala and was not able to see any resolver for java.util.Map
