Hi all,
You've probably found solution already but for future reference: I fixed it with converting activityByProduct DataFrame to RDD before calling .map:
activityByProduct.rdd.map { r =>
((r.getString(0), r.getLong(1)),
ActivityByProduct(r.getString(0), r.getLong(1), r.getLong(2), r.getLong(3), r.getLong(4)))
}
