Subject [jira] [Created] (KAFKA-6229) Controller node is not switched in ZK when existing is blocked using iptables
Date Fri, 17 Nov 2017 17:52:00 GMT
Navdeep Brar created KAFKA-6229:
-----------------------------------

             Summary: Controller node is not switched in ZK when existing is blocked using
iptables
                 Key: KAFKA-6229
                 URL: https://issues.apache.org/jira/browse/KAFKA-6229
             Project: Kafka
          Issue Type: Bug
            Reporter: Navdeep Brar


When controller node is blocked on network, ZK has no information that controller went down
and doesn't switch to new controller (other broker). 

 - This only happens when connection is blocked using iptables
 - if kafka service is brought down on controller node or even killed, then ZK very well acknowledges
it and switches to new controller
