             Summary: Consider adding SSL support for Spark REST submission server and client
                 Key: SPARK-20982
                 URL: https://issues.apache.org/jira/browse/SPARK-20982
             Project: Spark
          Issue Type: Improvement
          Components: Spark Submit
    Affects Versions: 2.2.0
            Reporter: Saisai Shao
            Priority: Minor


Currently all the Spark's http connection is secured by SSL except REST submission client and server used in Standalone and Mesos cluster mode. This could potentially be a security hole when running in a fully secured environment. Though this REST client and server are not public, only used by {{SparkSubmit}} internally, since it opened a http connection, so user could still use it bypass {{SparkSubmit}}.

So here proposed to SSL support for {{RestSubmissionClient}} and {{RestSubmissionServer}}.

CC [~tgraves] [~vanzin], what's your opinion on this? Would be grateful to see your comments.
