Anirban Das commented on SPARK-21331:
-------------------------------------
The code works fine on spark-shell as you saw. But the problem happens when you
use sbt run to run it (after using sbt package). I think the issue is with sbt
and MLlib.
> java.lang.NullPointerException for certain methods in classes of MLlib

> Key: SPARK-21331
> URL: https://issues.apache.org/jira/browse/SPARK-21331
> 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.
> Reporter: Anirban Das
>
> 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.
