stanislavkozlovski commented on pull request #7498: KAFKA-9023: Log request
destination when the Producer gets disconnected
URL: https://github.com/apache/kafka/pull/7498
When diagnosing network issues, it is useful to have a clear picture of
which client disconnected from which broker at what time.
Previously, when the producer received a NETWORK_EXCEPTION in its responses,
it would not log the node which disconnected.

> 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
