parallel processing that is the foundation of most of the above algorithms. We
cover other algorithms in our book and if you search on google you will find a
number of other examples.

Have a look at SPARK-9484, JIRA is already there. Pull request would be good.

I used the following build command:
build/mvn -Pyarn -Phadoop-2.4 -Dhadoop.version=2.4.0 -DskipTests clean package
this also gave the ‘Dependency-reduced POM’ loop

You’ll need to create a LinearRegressionWithSGD instance and set the step size
explicitly:
val lr = new LinearRegressionWithSGD()
