> In the AdminClient, if the initial ApiVersion request sent to the broker fails, we see
the following obscure message:
> {code}
> [2017-11-30 17:18:48,677] ERROR Internal server error on -2: server returned information
about unknown correlation ID 0.  requestHeader = {api_key=18,api_version=1,correlation_id=0,client_id=adminclient-3}
(org.apache.kafka.clients.admin.KafkaAdminClient)
> {code}
> What's happening is that the response to the internal ApiVersion request which is received
in NetworkClient is mistakenly being sent to the upper layer (the admin client in this case).
The admin wasn't expecting it, so we see this message. Instead, the request should be handled
internally in NetworkClient.
