---------------------------------------
I'll see if I can find a quick fix for this flakiness.
> Flaky test
> EosIntegrationTest.shouldWriteLatestOffsetsToCheckpointOnShutdown[at_least_once]
> -------------------------------------------------------------------------------------------
>
> Key: KAFKA-13690
> URL: https://issues.apache.org/jira/browse/KAFKA-13690
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Reporter: A. Sophie Blee-Goldman
> Priority: Major
>
> The _at_least_once_ version of the
> "{*}EosIntegrationTest.shouldWriteLatestOffsetsToCheckpointOnShutdown"{*}
> test is occasionally failing with
> h3. Error Message
> java.lang.AssertionError: The committed records do not match what expected
> Expected: <[KeyValue(0, 0), KeyValue(0, 1), KeyValue(0, 3), KeyValue(0, 6),
> KeyValue(0, 10), KeyValue(0, 15), KeyValue(0, 21), KeyValue(0, 28),
> KeyValue(0, 36), KeyValue(0, 45)]> but: was <[KeyValue(0, 0), KeyValue(0, 1),
> KeyValue(0, 3), KeyValue(0, 6), KeyValue(0, 10), KeyValue(0, 10), KeyValue(0,
> 11), KeyValue(0, 13), KeyValue(0, 16), KeyValue(0, 20), KeyValue(0, 25),
> KeyValue(0, 31), KeyValue(0, 38)]>
>
> Seems we are receiving more than the expected records.
> ...of course, this is an ALOS flavor of the {*}EOS{*}IntegrationTest, so
> perhaps we shouldn't be running this variant at all? Not sure if this
> explains the exact output we receive but it certainly seems suspicious
>
> Added at_least_once in [https://github.com/apache/kafka/pull/11283]
