https://community.cloudera.com/t5/Support-Questions/Configuring-two-listeners-in-Kerberized-Kafka/m-p/270086#M207279 <P>Sorry <a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/34938">@ManuelCalvo</a>&nbsp;, I probably have no time to do that because the test environment has been torn down. And I kind of have a theory for that. I guess that Kerberos principals are based on hostnames while I have changed Kafka listeners to IP addresses. With that config, Kafka clients cannot build a qualified principal name because they do not know hostnames of brokers. Thanks for you help anyway !</P> Tue, 10 Sep 2019 01:58:20 GMT iamabug 2019-09-10T01:58:20Z
