Hello everybody, I've opened a Jira to fix a bug on creation of internal topics. This happens when the topics are created under insufficient ACLs: eg. __consumer_offset is created but subsequent updateMetadata and leaderIsr requests fail; the topic is than in an inconsistent state and it is impossible to consume.
Jira: https://issues.apache.org/jira/browse/KAFKA-9806 A simple fix to solve this problem is to authorize the cluster operation before creating these topics. I've submitted a PR with the fix: https://github.com/apache/kafka/pull/8415 Please take a look and let me know if you have any feedback. Thanks, Paolo
