> Hi all,
>
> During kafka upgrade from 5.3.1 to 6.1.1.1 we get below error starting
> kafka-connector services
>
> ERROR [Worker clientId=connect-1, groupId=connect-cluster] Uncaught exception
> in herder work thread, exiting:
> (org.apache.kafka.connect.runtime.distributed.DistributedHerder)
> 87738-org.apache.kafka.common.config.ConfigException: Topic 'connect-offsets'
> supplied via the 'offset.storage.topic' property is required to have
> 'cleanup.policy=compact' to guarantee consistency and durability of source
> connector offsets, but found the topic currently has 'cleanup.policy=delete'.
> Continuing would likely result in eventually losing source connector offsets
> and problems restarting this Connect cluster in the future. Change the
> 'offset.storage.topic' property in the Connect worker configurations to use a
> topic with 'cleanup.policy=compact'.
>
> After that error we added log.cleanup.policy=compact parameter on
> /etc/kafka/server.properties and kafka-connector service started but a few
> days later all the connectors are down with attached error.
>
> Could you please let us know how we can resolved the issue?
>
> Best regards and thanks
