[kafka] Error sending message when leader is not master node

[#1]

Hi,

My current setup has 1 management node and 3 worker node.
Server A(master) - kafka broker, ...
Server B - zookeeper, kafka broker, ...
Server C - zookeeper, kafka broker, ...
Server D - zookeeper, kafka broker, ...

KAFKA-3.0.0-1.3.0.0.p0.40
CDH-5.14.2-1.cdh5.14.2.p0.3

I am using a client machine in the same network to create topic, produce and consume message using kafka bat files.

I realise when i create a topic, and the leader of the topic happens to be the broker on server A, everything works.

But if the leader of the topic is any broker on server b/c/d, when i attempt to send any messages, it prompt the following message.
WARN - Got error produce response with correlation id _ on topic-partition ___, retrying. Error: UNKNOWN_TOPIC_OR_PARTITION
WARN - Receive unknown topic or partition error in produce request on partition ___. The topic/partition may not exist or the user may not have Describe access to it
ERROR - Error when sending message to topic ___ with key: null, value... UnknownTopicOrPartitionException: This server does not host this topic-partition.

I am suspecting something to do with the zookeeper, but have no idea where to look deeper into.
I am a beginner in this area, any help would be appreciated.

Thanks in advance!

Manage to get it to work after putting broker and zookeeper on different node.
Not sure what is the reason, if anyone know please advise. Thanks!

Apologies, kafka broker can be same node as the zookeeper. Tested ok.

My issue was due to dns
Host file not set properly.
Pardon me.
