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

             Summary: Kafka 0.11.0.1 Kafka consumer/producers retries in 
infinite loop when wrong SASL creds are passed
                 Key: KAFKA-5910
                 URL: https://issues.apache.org/jira/browse/KAFKA-5910
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 0.11.0.0
            Reporter: Ramkumar


Similar to https://issues.apache.org/jira/browse/KAFKA-4764 , but the status 
shows patch available but the client wont disconnects after getting the warning.


Issue 1:
Publisher flow:
Kafka publisher goes into infinite loop if the AAF credentials are wrong when 
authenticating in Kaka broker.
Detail:
If the correct user name and password are used at the kafka publisher client 
side to connect to kafka broker, then it authenticates and authorizes fine.
If  incorrect username or password is used at the kafka publisher client side, 
then broker logs shows a continuous (infinite loop)  log showing client is 
trying to reconnect the broker as it doesn’t get authentication failure 
exception from broker. 
JIRA defect in apache:
https://issues.apache.org/jira/browse/KAFKA-4764

Can you pls let me know if this issue is resolved in kafka 0.11.0.1 version or 
still an open issue?
