> After the BulkWriterConfig broadcast refactor, bulk writer’s context/cluster/config subclasses cannot be instantiated on executors. For any job whose driver-side context was instantiated from a subclass, the executor silently instantiates base class implementations. Hence need to add the ability to broadcast and reconstruct subclasses on executors.
