Dear All, I'm trying to cluster data from native library code with Spark Kmeans||. In my native library the data are represented as a matrix (row = number of data and col = dimension). For efficiency reason, they are copied into a one dimensional scala Array row major wise so after the computation I have a RDD[Array[Double]] but the dimension of each array represents a set of data instead of the data itself. I need to transfrom these array into Array[Array[Double]] before running the KMeans|| algorithm.
How to do this efficiently ? Best regards,
