> Spark does not use SSL for HTTP File Server and Broadcast Server
> ----------------------------------------------------------------
>
> Key: SPARK-21346
> URL: https://issues.apache.org/jira/browse/SPARK-21346
> Project: Spark
> Issue Type: Question
> Components: Documentation, Spark Core
> Affects Versions: 2.1.1
> Reporter: John
> Priority: Minor
> Labels: documentation
>
> 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.
