I think, that calling a JoinFunction inside a RichMapRunner make sence. I
would also prefer not to touch the code generation if it's possible.
But shouldn't we separate the support of all inner joins with a single row
input from this "NOT IN" pull request? We might create a new jira issue to do
this in another pull request.
What do you think?
