[jira] [Commented] (KAFKA-9824) Consumer loses partition offset and
resets post 2.4.1 version upgrade
[ https://issues.apache.org/jira/browse/KAFKA-9824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17076491#comment-17076491 ]
Boyang Chen commented on KAFKA-9824:
------------------------------------
Thanks for reporting. Does the lost partition happen after each rebalance?

> Hello,
> around 2 weeks ago we upgraded our Kafka clients & brokers to 2.4.1 (from 2.3.1),
> and we started noticing a troubling behavior that we didn't see before:
>
> Without apparent reason, a specific partition on a specific consumer loses its offset and start re-consuming the entire partition from the beginning (according to the retention).
>
> Messages appearing on the consumer (client):

> The recovery you are seeing is after I run partition offset reset manually (using kafka-consumer-groups.sh --bootstrap-server localhost:9092 --topic trackingSolutionAttribution:57 --group fireAttributionConsumerGroup4 --reset-offsets --to-datetime 'SOME DATE')
