Hello, I was looking into the security options for the RPC server implementation (org.apache.hadoop.ipc.Server). As far as I understood, it supports SASL, either Kerberos authentication or no authentication (simple) and three QoP options.
I'd be interested to have a secure communication channel using SSL certificates instead of Kerberos. Do you know if there is any plan for future support of SSL? Currently I'm doing a preliminary research and I haven't really dig into SASL itself, but is it possible to use the current implementation of the server with SASL, but instead of Kerberos use SSL for authentication and channel encryption? Also, there seems to be the TOKEN - Digest-MD5 authentication method but according to the documentation this is not an option. Thank you for your time, -- Αντώνης Κουζούπης Antonios Kouzoupis
