Next, we will convert the preceding dataframe into an RDD:

val customerWeaponsSystemPairRDD: RDD[(Int, Int)] = customerWeaponsSystemDf.rdd.map(row =>                                                                (row.getInt(0),                                                                          row.getInt(1))                                                        )/*Notes: As far as the algorithm is concerned, customer corresponds to "user" and "product" or item corresponds to a "weapons ...
