问题
I have searched it all over and couldn't find the error. I have checked This Stackoverflow Issue but it is not the problem with me
I have started a zookeeper server
Command to start server was
bin/zookeeper-server-start.sh config/zookeeper.properties
Then I SSH into VM by using Putty and started kafka server using
$ bin/kafka-server-start.sh config/server.properties
Then I created Kafka Topic and when I list the topic, it appears.
- Then I opened another putty and started kafka-console-producer.sh and typed any message (even enter) and get this long repetitive exception.
Configuration files for zookeeper.properties, server.properties, kafka-producer.properties are as following (respectively)
The version of Kafka i am running is 8.2.2. something as I saw it in kafka/libs folder. P.S. I get no messages in consumer.
Can any body figure out the problem? The tutorial I was following was [This][9]

On the hortonworks sandbox have a look at the server configuration:
$ less /etc/kafka/conf/server.properties
In my case it said
...
listeners=PLAINTEXT://sandbox.hortonworks.com:6667
...
This means you have to use the following command to successfully connect with the console-producer
$ cd /usr/hdp/current/kafka-broker
$ bin/kafka-console-producer.sh --topic test --broker-list sandbox.hortonworks.com:6667
It won't work, if you use --broker-list 127.0.0.1:6667 or --broker-list localhost:6667 . See also http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_installing_manually_book/content/configure_kafka.html
To consume the messages use
$ bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test --from-beginning

As you mentioned in your question that you are using HDP 2.3 and for that when you are running Console-Producer
You need to provide sandbox.hortonworks.com:6667 in Broker-list.
Please use the same while running Console-Consumer.
Please let me know in case still you face any issue.

Within Kafka internally there is a conversation that goes on between both producers and consumers (clients) and the broker (server). During those conversations clients often ask the server for the address of a server broker that's managing a particular partition. The answer is always a fully-qualified host name. Without going into specifics if you ever refer to a broker with an address that is not that broker's fully-qualified host name there are situations when the Kafka implementation runs into trouble.
Another mistake that's easy to make, especially with the Sandbox, is referring to a broker by an address that's not defined to the DNS. That's why every node on the cluster has to be able to address every other node in the cluster by fully-qualified host name. It's also why, when accessing the sandbox from another virtual image running on the same machine you have to add sandbox.hortonworks.com to the image's hosts file.
