------------------------------------------

             Summary: Producer NETWORK_EXCEPTION response should log more information
                 Key: KAFKA-9023
                 URL: https://issues.apache.org/jira/browse/KAFKA-9023
             Project: Kafka
          Issue Type: Improvement
            Reporter: Stanislav Kozlovski
            Assignee: Stanislav Kozlovski


When diagnosing network issues, it is useful to have a clear picture of which client disconnected from which broker at what time.
Currently, when the producer receives a NETWORK_EXCEPTION in its responses, it logs the following:
{code:java}
[Producer clientId=<CLIENT>] Received invalid metadata error in produce request on partition <partition> due to org.apache.kafka.common.errors.NetworkException: The server disconnected before a response was received.. Going to request metadata update now {code}
It would be good if we logged additional information regarding the broker/host whose connection was disconnected
