[jira] [Commented] (KAFKA-5222) Kafka Connection error in
contoller.logs
[ https://issues.apache.org/jira/browse/KAFKA-5222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16007742#comment-16007742 ]
huxi commented on KAFKA-5222:
-----------------------------
Did you set `broker.id` in server.properties? I wonder where the `Connection to 1` comes from if you did not set this config and only one broker is started since the default broker is starts from zero.
