The build side hinted here is also the constant (loop invariant) side,
correct?

> Project: Flink
> Issue Type: Bug
> Components: Machine Learning Library
> Reporter: Till Rohrmann
> Priority: Minor
> Labels: ML
>
> Using the {{predict}} or {{empiricalRisk}} function of the {{ALS}} class can
> cause the Flink job to fail with a {{Hash join exceeded maximum number of
> recursions}} exceptions. This is due to a wrong build side for the hash join
> operation.
> This bug should be fixable by setting the correct join hints.
