[jira] [Commented] (KAFKA-13165) Validate node id, process role and quorum voters

["Colin McCabe (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-13165?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17393313#comment-17393313 ] 

Colin McCabe commented on KAFKA-13165:
--------------------------------------

The node ID space of controllers and brokers is disjoint. So we cannot find out anything useful by checking if the broker's node.id is in controller.quorum.voters.

Brokers should be observers in the raft quorum, so I don't see how the broker becoming a leader could be a problem. Maybe this is a loophole we need to close. We should be able to tell the RaftClient whether it is an observer or a voter.

> Under certain configuration is possible for the Kafka Server to boot up as a broker only but be the cluster metadata quorum leader. We should validate the configuration to avoid this case.
>  # If the {{process.roles}} contains {{controller}} then the {{node.id}} needs to be in the {{controller.quorum.voters}}
>  # If the {{process.roles}} doesn't contain {{controller}} then the {{node.id}} cannot be in the {{controller.quorum.voters}}
