             Summary: RackId doesn't exist while running WordCountDemo
                 Key: KAFKA-15491
                 URL: https://issues.apache.org/jira/browse/KAFKA-15491
             Project: Kafka
          Issue Type: Bug
          Components: streams
            Reporter: Luke Chen


While running the WordCountDemo following the 
[docs|https://kafka.apache.org/documentation/streams/quickstart], I saw the 
following error logs in the stream application output. Though everything still 
works fine, it'd be better there are no ERROR logs in the demo app.
