Description

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.
