---------------------------------
Assignee: Philip Nee (was: Kirk True)
> Compatibility break in Admin.listOffsets()
> ------------------------------------------
>
> Key: KAFKA-12879
> URL: https://issues.apache.org/jira/browse/KAFKA-12879
> Project: Kafka
> Issue Type: Bug
> Components: admin
> Affects Versions: 2.8.0, 2.7.1, 2.6.2
> Reporter: Tom Bentley
> Assignee: Philip Nee
> Priority: Major
>
> KAFKA-12339 incompatibly changed the semantics of Admin.listOffsets().
> Previously it would fail with {{UnknownTopicOrPartitionException}} when a
> topic didn't exist. Now it will (eventually) fail with {{TimeoutException}}.
> It seems this was more or less intentional, even though it would break code
> which was expecting and handling the {{UnknownTopicOrPartitionException}}. A
> workaround is to use {{retries=1}} and inspect the cause of the
> {{TimeoutException}}, but this isn't really suitable for cases where the same
> Admin client instance is being used for other calls where retries is
> desirable.
> Furthermore as well as the intended effect on {{listOffsets()}} it seems that
> the change could actually affect other methods of Admin.
> More generally, the Admin client API is vague about which exceptions can
> propagate from which methods. This means that it's not possible to say, in
> cases like this, whether the calling code _should_ have been relying on the
> {{UnknownTopicOrPartitionException}} or not.
