>                 URL: https://issues.apache.org/jira/browse/KAFKA-7958
>             Project: Kafka
>          Issue Type: Bug
>    Affects Versions: 2.1.0
>         Environment: cp-kakfka 2.1.1-1, kafka-streams 2.1.1
>            Reporter: Thomas Dickinson
>            Priority: Major
>
> After a rolling re-start in a kubernetes-like environment, brokers may change 
> IP address.  From our logs it seems that the transaction manager in the 
> brokers never re-resolves the DNS name of other brokers, keeping stale pod 
> IPs.  Thus transactions stop working.

> This is from the log from broker 1001 which was restarted first, followed by 
> 1 and then 0.  The log entries are from the day after the rolling restart.
> I note a similar issue was fixed for clients 2.1.1  
> https://issues.apache.org/jira/browse/KAFKA-7755.  We are using streams lib 
> 2.1.1
> We have turned off EOS in our stream applications to work-around this issue.
