Newbie question... Can I use any of the main ML capabilities of MLlib in a Java-only environment, without any native library dependencies?
According to the documentation, java-netlib provides a JVM fallback. This suggests that native netlib libraries are not required. It appears that such a fallback is not available for jblas. However, a quick look at the MLlib source suggests that MLlib's dependencies on jblas are rather isolated: > grep -R jblas main/scala/org/apache/spark/ml/recommendation/ALS.scala:import org.jblas.DoubleMatrix main/scala/org/apache/spark/mllib/optimization/NNLS.scala:import org.jblas.{DoubleMatrix, SimpleBlas} main/scala/org/apache/spark/mllib/recommendation/MatrixFactorizationModel.scala:import org.jblas.DoubleMatrix main/scala/org/apache/spark/mllib/util/LinearDataGenerator.scala:import org.jblas.DoubleMatrix main/scala/org/apache/spark/mllib/util/LinearDataGenerator.scala: org.jblas.util.Random.seed(42) main/scala/org/apache/spark/mllib/util/MFDataGenerator.scala:import org.jblas.DoubleMatrix main/scala/org/apache/spark/mllib/util/SVMDataGenerator.scala:import org.jblas.DoubleMatrix Is it true or false that many of MLlib's capabilities will work perfectly fine without any native (non-Java) libraries installed at all?
