Description

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.
