Subject Re: KafkaStreams: ProducerFencedException causing StreamThread death
Date Fri, 28 Sep 2018 23:45:37 GMT
Hello Aravind,

Which version of Kafka are you currently using? What you described seems to
be fixed in the latest version already, so I want to check if you are using
an older version and if yes, what's the best way to work around it.
