Hi all, We found a blocker in 2.0.0 which is a bug in the newly added OAuth protocol implementation (https://issues.apache.org/jira/browse/KAFKA-7182). Since the current implementation doesn't conform to the SASL/OAUTHBEARER spec in RFC-7628, we need to fix this before the release to conform to the spec and avoid compatibility issues later. A fix is currently being reviewed and I will try and create RC3 later today.
Many thanks to everyone who tested and voted for RC2. Please help test RC3 if you have time. Regards, Rajini On Wed, Jul 18, 2018 at 4:03 PM, Guozhang Wang <wangg...@gmail.com> wrote: > +1.
