>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.4.0

>            Priority: Minor

> There's code in {{SecurityManager}} that is used to configure SSL for the code that downloads dependencies from https servers:
> {code}
>   // SSL configuration for the file server. This is used by Utils.setupSecureURLConnection().
>   val fileServerSSLOptions = getSSLOptions("fs")
>   val (sslSocketFactory, hostnameVerifier) = if (fileServerSSLOptions.enabled) {
>     ...
> {code}
> It was added for an old feature that doesn't exist anymore (the "file server" referenced in the comment), but can still be used to configure the built-in JRE SSL code with a custom trust store, for example.
> We should instead:
> - move this code out of SecurityManager, and place it where it's actually used ({{Utils.setupSecureURLConnection}}.
> - remove the dummy trust manager / host verifier since they don't make a lot of sense for the client code (and only made slightly more sense for the file server case).
