This `TimeUnit.DAYS.toMillis(1)` was supposed to achieve exactly what we're having to do by setting a higher `RETRY_BACKOFF_MS_CONFIG`. The `createPendingAuthenticationError` takes the backoff param and sets it as the backoff for the node https://github.com/apache/kafka/blob/97a228070e7711f7547e245d82771f9b81dda96d/clients/src/test/java/org/apache/kafka/clients/MockClient.java#L170 So the MockClient shouldn't generate a new fetchMetadata for 1 day I expect. https://github.com/apache/kafka/blob/97a228070e7711f7547e245d82771f9b81dda96d/clients/src/test/java/org/apache/kafka/clients/MockClient.java#L606 That being said, agree with @AndrewJSchofield 's suggestion, we could add the config to stabilize the very noisy test, and have a follow-up jira to check why the MockClient is requiring an explicit backoff config in this case. -- This is an automated message from the Apache Git Service.
