Is it fair to assume this is what I need?

As far as I know spark does not implement such algorithms. In case the dataset
is small

I think you look more for algorithms for unsupervised learning, eg clustering.
Depending on the characteristics different clusters might be created , eg donor
or non-donor. Most likely you may find also more clusters (eg would donate but
has a disease preventing it or too old). You can verify which clusters make
sense for your approach so I recommend not only try two clusters but multiple
and see which number is more statistically significant .

I'm attempting to create a training classification, but only have positive
information.  Specifically in this case it is a donor list of users, but I want
to use it as training in order to determine classification for new contacts to
give probabilities that they will donate.
Any insights or links are appreciated. I've gone through the documentation but
have been unable to find any references to how I might do this.
