Description

if trotting is triggered on a broker, then the client receives something like this:

org.apache.kafka.clients.FetchSessionHandler.handleResponse

FetchResponse 
 throttleTimeMs = 2583
 error = {Errors} "NONE"
 sessionId = 0
 responseData = {LinkedHashMap}  size = 0 

which in the logs looks like:

[INFO ] o.a.k.c.FetchSessionHandler  [Consumer clientId=dev, groupId=null] Node 18 sent an invalid full fetch response with extra=(topicName-11, response=( 

It would be great to see the reason and parameter throttleTimeMs in the logs!
