Rajini Sivaram commented on KAFKA-3618:
---------------------------------------

[~junrao] [~ijuma] I have the server-side code ready (built on top of the PR in KAFKA-3307), but wasn't sure if we also want the Java client to request API versions in the SASL client authenticator. At the moment, there is no real reason to make the client changes since there is only one version of SaslHandshakeRequest and hence a version request before the handshake doesn't add much value. But if required for 0.10.0, I can work on those changes now (on a different PR since the client changes will be built on top of the PR from KAFKA-3600). Thanks.

> Handle ApiVersionRequest in SaslServer authenticator before SaslHandshakeRequest to enable clients to obtain handshake request version from the server. This should be implemented after KAFKA-3307 which adds support for version requests after authentication and KAFKA-3149 which adds handshake requests.
