Sorry, I wasn't aware of that. Do you mind elaborating more on what kind of resources are
fetched using HTTPS? I'd be happy to make a PR but I'd just like a little more information.

> SecurityManager states that SSL is used to secure HTTP communication for the broadcast
and file server. However, the SSLOptions from the SecurityManager only seem to be used by
the SparkUI, the WebUI, and the HistoryServer. According to  [Spark-11140|https://issues.apache.org/jira/browse/SPARK-11140]
and [Spark-12588|https://issues.apache.org/jira/browse/SPARK-12588], neither the file server
nor broadcast use HTTP anymore. It seems that the documentation is inaccurate and that Spark
actually uses SASL on the RPC endpoints to secure the file server and broadcast communications.
