Brandon Barker resolved SPARK-20497.
------------------------------------
Resolution: Not A Bug
> Unhelpful error messages when trying to load data from file.
> ------------------------------------------------------------
>
> Key: SPARK-20497
> URL: https://issues.apache.org/jira/browse/SPARK-20497
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Brandon Barker
> Priority: Minor
>
> I'm attempting to do the simple task of reproducing the results from the
> linear regression example in Spark. I'm using Windows 10.
> val training = spark.read.format("libsvm")
> .load("C:Users\\brand\\Documents\\GitHub\\sample_linear_regression_data.txt")
> Although the file is definitely at the specified location, I just get a
> java.lang.NullPointerException at this line. The documentation at
> http://spark.apache.org/docs/latest/sql-programming-guide.html#generic-loadsave-functions
> doesn't seem to clear things up. The associated javadocs do do not seem any
> better.
> In my view, such a simple operation should not be troublesome, but perhaps
> I've missed some critical documentation - if so, I apologize.
