> ERROR org.apache.kafka.connect.runtime.distributed.DistributedHerder [Worker
> clientId=connect-1, groupId=connect-cluster] Uncaught exception in herder
> work thread, exiting:
> org.apache.kafka.connect.errors.ConnectException: Error while attempting to
> create/find topic(s) 'connect-offsets'

> Caused by: java.util.concurrent.ExecutionException:
> org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication
> factor: 3 larger than available brokers: 2.
