Marcelo Vanzin commented on SPARK-20982:
----------------------------------------

Really not familiar with that stuff. But given that it uses Jetty most probably, I'm surprised it doesn't support ssl.

> 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.
