Hi everyone is it possible to return multiple values with an udaf defined in spark 1.5.0? The documentation [1] mentions
abstract def dataType: DataType The DataType of the returned value of this UserDefinedAggregateFunction. so it's only possible to return a single value. Should I use ArrayType as a WA here? The returned values are all doubles.
