Hi , I am a Spark 1.5 user and currently do some testing on Spark-shell. When I execute a SQL query using UDF returning Map type in Java, spark-shell returns an error message saying that MapType is Java is unsupported. So I wonder whether it is possible to convert MapType in Java to MapType in scala or any other types supported in below link: http://spark.apache.org/docs/latest/sql-programming-guide.html#data-types Or there is no way to do so? Thanks
Regards, BaiChuan Yang
