Hi I have never dabbled Kafka with security settings. I was trying to follow this blog to get it working: http://kafka.apache.org/documentation.html#security_sasl
But I can't seem to add principals for Kafka in Kerberos server, and I am getting the following error: dp@kdc:~$ sudo /usr/sbin/kadmin.local -q 'addprinc -randkey kafka/ kaf...@example.com' [sudo] password for dp: Authenticating as principal root/ad...@example.com with password. WARNING: no policy specified for kafka/kaf...@example.com; defaulting to no policy add_principal: No such entry in the database while creating "kafka/ kaf...@example.com". dp@kdc:~$ ^C Can anyone share more insight into how they got a simple Kerberos server to work with Kafka, and able to send one message end to end. I greatly appreciate your help. Many thanks. -- Raghav
