It is recommended that Spark users upgrade to using TLS for RPC calls between Spark processes. This protocol +will be deprecated and removed in the long-term. + +See +the [Spark security documentation](https://github.com/apache/spark/blob/master/docs/security.md#ssl-encryption) for +more information on how to configure TLS. Review Comment: I am not sure if we should announce deprecation given TLS is going to come out only in 4.0 ... we can recommend users to move to TLS. Would like feedback from others on this though ... @dongjoon-hyun, @srowen, @JoshRosen -- This is an automated message from the Apache Git Service.
