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

             Summary: Kafka with 2.7.0 version service start failing while 
making zookeeper connection calls
                 Key: KAFKA-12745
                 URL: https://issues.apache.org/jira/browse/KAFKA-12745
             Project: Kafka
          Issue Type: Bug
          Components: controller, zkclient
    Affects Versions: 2.7.0
         Environment: production
            Reporter: Ramesh Sencha


I have existing Kafka setup working as below -

{code} 

{{Kafka - 2.4.1 (3 brokers)}}

{{Zookeeper - 3.6.2 (3 nodes)}}

{code}

{{}}

Now I am upgrading the Kafka version to 2.7.0, but when I downloaded the binary 
and trying to start service, it is failing while making the connection with the 
zookeeper, it's not giving many error details/trace, only below logs.

I tried to set logging mode to DEBUG but still not giving much information on 
why it's not able to make the connection with the zookeeper, from logs it's 
clear that it has initiated a zookeeper connection.

Another thing which I suspect is why it is giving zookeeper version 3.4.13 when 
my zookeeper server(which is on another machine) is version 3.6.2

{code}

 {{INFO Client 
environment:zookeeper.version=3.4.13-2d71af4dbe22557fda74f9a9b4309b15a7487f03, 
built on 06/29/2018 00:39 GMT (org.apache.zookeeper.ZooKeeper)}}

{code}

 

If I switch back to using Kafka 2.4.1 & everything else as is it works fine, 
but not sure whats the problem with Kafka version 2.7.x/2.6.x

Any help would be greatly appreciated.
