             Summary: Admin can transiently return incorrect results about topics
                 Key: KAFKA-10206
                 URL: https://issues.apache.org/jira/browse/KAFKA-10206
             Project: Kafka
          Issue Type: Bug
          Components: admin, core
            Reporter: Tom Bentley
            Assignee: Tom Bentley


When a broker starts up it can handle metadata requests before it has 
received UPDATE_METADATA requests from the controller. 
This manifests in the admin client via:

* listTopics returning an empty list
* describeTopics and describeConfigs of topics erroneously returning TopicOrPartitionNotFoundException

I assume this also affects the producer and consumer, though since `UnknownTopicOrPartitionException` is retriable those clients recover.

Testing locally suggests that the window for this happening is typically <1s.

There doesn't seem to be any way for the caller of the Admin client to detect this situation.
