[jira] [Updated] (KAFKA-1945) MetaData Response - Broker hostname is wrong

["saravana kumar (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/KAFKA-1945?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

saravana kumar updated KAFKA-1945:
----------------------------------
    Description: 
I use python-kafka's SimpleConsumer to listen to a topic in kafka broker. Kafka broker is running on a machine with its hostname as BROKER_HOST. Now, SimpleConsumer from another machine requests for topic metadata from the broker BROKER_HOST for a topic TOPIC & gets a python tuple

   (Broker metadata, Topic metadata)
Broker metadata comes as,

 {0: BrokerMetadata(nodeId=0, host='localhost', port=9092)}

ideally, host value must be BROKER_HOST("hostname" cmd from broker shell tty confirms it) but it comes as localhost...

How does the wrong broker metadata for a topic get into kafka system? And obviously, this breaks the system since my consumer tries to connect to 9092 on its localhost.
