Dmitri Pavlov commented on KAFKA-17704:
---------------------------------------
And a short comment as per the log provided. Why there are no "Starting task"
entries after 9:24:38. At 9:24 (after 10 minutes TTL at at 9:14) the config got
refreshed and new creds loaded. Though looks like the settings did not
propagate down to tasks. !image-2024-10-07-11-17-41-951.png!

> Key: KAFKA-17704
> URL: https://issues.apache.org/jira/browse/KAFKA-17704
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 3.7.1
> Reporter: Doug Whitfield
> Priority: Minor
> Attachments: image-2024-10-07-11-17-41-951.png, logstoupload.log

>
> This is related to https://issues.apache.org/jira/browse/KAFKA-9228 and
> https://issues.apache.org/jira/browse/KAFKA-17627 but in single node instance
> and only related to credentials (as far as we know currently), so maybe
> something else is in play?
> In some cases, when TTL is used with a single node, passwords are not passed
> properly.
> In the "logstoupload.log" file you can see that at 09:14 the password does
> not get change, but at 09:24 it does get changed.
> We are able to "reliably" reproduce this in prod-like environment where this
> log comes from in Kubernetes, but we have only captured this "race condition"
> in test rarely where we are not using Kubernetes. We have seen it without
> Kubernetes though.
> We hope to provide something more reproducible next week, but perhaps
> uploading this "full" log will allow you to guide us so we can make this more
> reproducible.
