I get an inexplicable exception when trying to build an ALSModel with the
implicit set to true. I can’t find any help online.
Thanks in advance.
My code is:

Weight values above?
Thanks.

Hi,
Can anyone recommend testing frameworks suitable for Spark jobs. Something
that can be integrated into a CI tool would be great.
Thanks.
