Review comment:
Agree, it is interesting that StreamJobFactory is only used in JobRunner,
and JobRunner is only used in RemoteApplicationRunner, i.e. StreamJobFactory is
only intended to be used for remote job, so RemoteJobPlanner technically fits
here. I agree we have excessive layers in our structure which should be
simplified to avoid future confusion.
