val trainRDD = rawTrainData.map( rawRow => Row( rawRow.split(",")
.map(_.toInt) ) )
The above is creating a Row with a single column that contains a sequence.
You need to extract the sequence using varargs:
val trainRDD = rawTrainData.map( rawRow => Row( rawRow.split(",")
.map(_.toInt): _* ))
You could also use Row.fromSeq:
val trainRDD = rawTrainData.map(rawRow => Row.fromSeq(rawRow.split(",")
.map(_.toInt)))
