[jira] [Commented] (AMBARI-20908) Kafka advertised.listeners replaced in Kerberos Mode

["Bharat Viswanadham (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-20908?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15993381#comment-15993381 ] 

Bharat Viswanadham commented on AMBARI-20908:
---------------------------------------------

With the patch one issue it will happen is if User has manually set listeners to advertised.listeners=PLAINTEXT://<<hostname>>:<<port>>, after enable kerberos, the user has to manually change the advertised.listeners to SASL_PLAINTEXT://<<hostname>>:<<port>>. Might be that is the reason in the code to use advertised.listeners as listeners. Any idea's on how to handle the user manually set case also?

> Install ambari with Kafka.
> 1. Add advertised.listeners to Kafka Config.
> 2. Restart Kafka.
> 3. Enable Kerberos.
> 4. After that advertised.listeners get replaced with listeners.
> This is happening, because of the code in common services in kafka.py. Even if advertised.listeners is not set, it automatically add's advertised.listeners to kafka config, which has same values as 
> if params.security_enabled and params.kafka_kerberos_enabled:
>          Logger.info("Kafka kerberos security is enabled.")
>          kafka_server_config['advertised.listeners'] = listeners
>          Logger.info(format("Kafka advertised listeners: {listeners}"))
