             Summary: add node advertised listeners  when AdminClient can not 
connect to the node
                 Key: KAFKA-14068
                 URL: https://issues.apache.org/jira/browse/KAFKA-14068
             Project: Kafka
          Issue Type: Improvement
            Reporter: Justinwins


When there is a node NOT available,we found a lot of log like :

[2022-07-12 17:05:26.403] [WARN] [kafka-admin-client-thread | adminclient-20] 
[c.v.p.middleware.kafka.clients.NetworkClient] >>> [AdminClient 
clientId=adminclient-20] Connection to node -1 could not be established. Broker 
may not be available.

 

If the app uses many admin clients when it connects many kafka clusters , it 
would be no easy thing to get exactly the crashed node as no node name or 
listener name

is in the log.
