>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 2.4.4

> The SQL configurations are propagated to executors in order to be effective.
> Unfortunately, in some cases, we are missing to propagate them, making them un-effective.
> The problem happens every time {{rdd}} or {{queryExecution.toRdd}} are used. And this is pretty frequent in the codebase.
> Please notice that there are 2 parts of this issue:
>  - when a user directly uses those APIs
>  - when Spark invokes them (eg. throughout the ML lib and other usages or the {{describe}} method on the {{Dataset}} class)
