Seems to me this is simply a user-user similarity problem where I have

The spark version of itemsimilarity only has LLR as a metric. But what about
RSJ? it’s a pretty simple thing to convert itemsimilarity to rowsimilarity but
RSJ has some uses beyond collaborative filtering. Are some of the other
similarity metrics needed?
Specifically text comparison typically
