Subject [jira] [Created] (SPARK-21346) Spark does not use SSL for HTTP File Server and Broadcast Server
Date Fri, 07 Jul 2017 22:35:00 GMT
John created SPARK-21346:
----------------------------

             Summary: 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


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.
