----------------------------------

FYI: I've just come across this behavior and raised a ticket so that we don't forget about it, but I'm not working on this one (yet).

> Following SPARK-18952 and SPARK-22273, this ticket proposes to change the generated field name of the keySchema / valueSchema to a dummy name instead of using {{key.name}}.
> In previous discussion from SPARK-18952's PR [1], it was already suggested that the field names were being used, so it's not worth capturing the strings as reference objects here. Josh suggested merging the original fix as-is due to backportability / pickability concerns. Now that we're coming up to a new release, this can be revisited.
