Hey All, I've been playing around with the new DataFrame and ML pipelines APIs and am having trouble accomplishing what seems like should be a fairly basic task.
I have a DataFrame where each column is a Double. I'd like to turn this into a DataFrame with a features column and a label column that I can feed into a regression. So far all the paths I've gone down have led me to internal APIs or convoluted casting in and out of RDD[Row] and DataFrame. Is there a simple way of accomplishing this? any assistance (lookin' at you Xiangrui) much appreciated, Sandy
