Hi ZK folks, I've just created a new ticket and a patch to disable the DIGEST-MD5 mech fallback when creating Sasl Client for quorum/clients. It's a legacy and hardcoded stuff to support DIGEST auth apart from Kerberos in SASL authentication and unfortunately it's widely used in our unit tests, hence the lots of unit test changes.
Please take a look. https://issues.apache.org/jira/browse/ZOOKEEPER-4889 https://github.com/apache/zookeeper/pull/2213 Thanks, Andor
