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

             Summary: High CPU issue in Kafka Producer when Auth Failed 
                 Key: KAFKA-15796
                 URL: https://issues.apache.org/jira/browse/KAFKA-15796
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 3.5.1, 3.6.0, 3.4.1, 3.5.0, 3.3.2, 3.3.1, 3.2.3, 3.2.2
            Reporter: xiaotong.wang


How to reproduce

1、kafka-client 3.x.x  Producer config  enable.idempotence=true  (this is default)

2、start kafka server , not contain client user auth info

3、start client producer , after 3.x，producer will initProducerId and TCM state trans to INITIALIZING
4、server reject client reqesut , producer will raise 
AuthenticationException  (org.apache.kafka.clients.producer.internals.Sender#maybeSendAndPollTransactionalRequest)
5、kafka-client org.apache.kafka.clients.producer.internals.Sender#runOnce catch
AuthenticationException 
      call transactionManager.authenticationFailed(e); 
    
     synchronized void authenticationFailed(AuthenticationException e) {
          for (TxnRequestHandler request : pendingRequests)
          request.fatalError(e);
      }
     this method only handle pendingRequest，but inflight request is miss 
6、 TCM state will alway in INITIALIZING
      for udgment Condition： currentState != State.INITIALIZING && !hasProducerId()
7、producer send mesasge , mesasge go into  batch queue，Sender will wake up and set pollTimeout=0 , prepare to send message 

8、but , before Sender sendProducerData ,it will do message filter ，RecordAccumulator drain -->drainBatchesForOneNode-->shouldStopDrainBatchesForPartition 
      when producerIdAndEpoch.isValid()==false，return true, it will not collect any message 
9、now kafka producer network thread  CPU useage will go 100%
10、even we add user auth info and permission in kafka server ,it can not self-healing
 
 
 
suggest : 
also catch AuthenticationException   org.apache.kafka.clients.producer.internals.Sender#maybeSendAndPollTransactionalRequest  and respone failed to inflight InitProducerId request
