--------------------------------------
Summary: possible race condition in TTL credentials when
connectors recycled on single node instance
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
Attachments: 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.
