Saisai Shao commented on SPARK-21346: ------------------------------------- SSL is still used for fetch remote resources from HTTPS. If you think the doc inaccurate, you could improve the docs by PR. > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
