In this recipe, we explore addition in the Spark environment using the Breeze
library for underlying operations. Vectors allow us to collect features and then manipulate them via linear algebra operations such as add, subtract, transpose, dot product, and so on.
- Start a new project in IntelliJ or in an IDE of your choice. Make sure that the necessary JAR files are included.
- Import the necessary packages for vector and matrix manipulation:
import org.apache.spark.mllib.linalg.distributed.RowMatrix import org.apache.spark.mllib.linalg.distributed.{IndexedRow, IndexedRowMatrix} import org.apache.spark.mllib.linalg.distributed.{CoordinateMatrix, MatrixEntry} import org.apache.spark.sql.{SparkSession} import org.apache.spark.mllib.linalg._ import breeze.linalg.{DenseVector => BreezeVector} import Array._ import org.apache.spark.mllib.linalg.DenseMatrix import org.apache.spark.mllib.linalg.SparseVector
- Set up the Spark session...
