> 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.
