---------------------------------------
[~iemejia] is this in progress? Is there a chance for it to be done for 2.17.0?
Is it a regression?

> that the Spark runner is not respecting the user defined Spark default
> parallelism configuration. We should investigate and if it is the case ensure
> that a user defined configuration is always respected. Runner optimizations
> should apply only for default (unconfigured) values otherwise we will confuse
> users and limit them from parametrizing Spark for their best convenience.
