Lars Francke commented on HIVE-18712:
-------------------------------------
gRPC is great but it does not support Kerberos authentication and I assume we
won't get away from Kerberos anytime soon. We'd need to do custom code (sending
a ticket as metadata) etc. also encryption would only really be possible using
TLS and not on the Kerberos/SASL layer. I'm not _against_ gRPC but it's
something we'd need to think about.
