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

             Summary: Incorrect listeners property in file 
/etc/kafka/conf/server.properties
                 Key: AMBARI-12427
                 URL: https://issues.apache.org/jira/browse/AMBARI-12427
             Project: Ambari
          Issue Type: Bug
          Components: stacks
    Affects Versions: 2.1.0
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
            Priority: Critical
             Fix For: 2.1.1


The file /etc/kafka/conf/server.properties that gets created after running the 
script upgradeHelper.py has the following property:

listeners=PLAINTEXT://hmcl-amb-201-hdp-2260-to-amb-21-hdp-2300-1-1:6667,PLAINTEXT://hmcl-amb-201-hdp-2260-to-amb-21-hdp-2300-1-4:6667

The value for this property is exactly the same in all the hosts running the 
kafka-broker, which causes the following exception in var/log/kafka/server.log

java.lang.IllegalArgumentException: requirement failed: Each listener must have 
a different port

The correct value for the listeners property should be HOST_NAME:PORT where 
HOST_NAME is the host name of the node corresponding to that kafka broker, and 
PORT is the kafka broker port

Please see attached screenshots for details.
