-----------------------------------------

Hi, I run the code in description on mac, spark-2.1.1. It works out 
successfully without any exception.

scala> val svd: SingularValueDecomposition[RowMatrix, Matrix] = 
mat.computeSVD(2, computeU = true)

> java.lang.NullPointerException for certain methods in classes of MLlib

>             Project: Spark
>          Issue Type: Bug
>          Components: Build, MLlib
>    Affects Versions: 2.1.0
>         Environment: Spark running locally on OSX at spark://127.0.0.1:7077.

> I am trying to run the following code using sbt package and sbt run. I am 
> getting a runtime error that seems to be a bug since the same code works 
> great on spark-shell with Scala. The error occurs when executing the 
> computeSVD line. If this line is commented out, the program works fine. I am 
> having similar issues for other methods for classes in MLlib as well. This 
> looks like a bug to me.
