Hi all, I'd like to report a bug for Connect this time.
System test runs revealed an issue when restarting a connector but not the tasks. You may find a description in: https://issues.apache.org/jira/browse/KAFKA-13139 The underlying issue is related to the implementation of KIP-745. This makes it a regression for 3.0 and given that it doesn't seem to have a viable workaround other than not using this specific functionality, I'm willing to consider it as a blocker for 3.0.0 if there are no objections. A PR is up for review: https://github.com/apache/kafka/pull/11132 Regards, Konstantine On Mon, Jul 26, 2021 at 9:15 AM Konstantine Karantasis < kkaranta...@apache.org> wrote: > > Hi Justine, > > Thanks for reporting this issue.
