Historical retrieval job often fails when the size of the entities are larger than what broadcast join can handle. The original intention of using broadcast join is to speed up the computation, assuming that the entities are small enough to be broadcasted, but that is rarely the case. It's also unclear at the moment on how much is the performance gain we can attain by using broadcast join.
Until more research is performed, we will disable broadcast join by default.
