[jira] [Created] (KAFKA-12431) Fetch Request/Response without Topic information

Peter Sinoros-Szabo created KAFKA-12431:
-------------------------------------------

             Summary: Fetch Request/Response without Topic information
                 Key: KAFKA-12431
                 URL: https://issues.apache.org/jira/browse/KAFKA-12431
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.6.1
            Reporter: Peter Sinoros-Szabo


I was running a 6 node Kafka 2.4.1 cluster with protocol and message format version set to 2.4. I wanted to upgrade the cluster to 2.6.1 and after I upgraded the 1st broker to 2.6.1 without any configuration change, I noticed much higher CPU usage on that broker (instead of 25% CPU usage it was  ~350%) and about 3-4x higher network traffic. So I dumped the traffic between the Kafka client and broker and compared it with the traffic of the same broker downgraded to 2.4.1.

It seems to me that after I upgraded to 2.6.1, the Fetch requests and responses are not complete, it is missing the topics part of the Fetch Request, I don't know for what reason. I guess there should be always a topics part.

I'll attache a screenshot from these messages.
