[jira] [Commented] (KAFKA-8430) Unit test to make sure `group.id`
and `group.instance.id` won't affect each other
[ https://issues.apache.org/jira/browse/KAFKA-8430?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16849923#comment-16849923 ]
Boyang Chen commented on KAFKA-8430:
------------------------------------
After checking the code in `KafkaConsumer`, I found out that the logic for null `group.id` is like
```// no coordinator will be constructed for the default (null) group id
this.coordinator = groupId == null ? null :(
new ConsumerCoordinator(logContext,```
So if `ConsumerCoordinator` is not constructed, `group.instance.id` is no use at all.
