Answer 1

Kafka is a distributed system and needs Zookeeper. you have to start zookeeper too. Follow "Quick Start" here : https://kafka.apache.org/0100/documentation.html#quickstart

Answer 2

You can try using the below two command and list all Kafka topic

• bin/kafka-topics.sh --describe --zookeeper 192.168.0.142:2181,192.168.9.115:2181,192.168.4.57:2181
• bin/kafka-topics.sh --zookeeper 192.168.0.142:2181,192.168.9.115:2181,192.168.4.57:218 --list

Answer 3

Commands:

1. To start the kafka:

   $ nohup ~/kafka/bin/kafka-server-start.sh ~/kafka/config/server.properties > ~/kafka/kafka.log 2>&1 &

2. To list out all the topic on on kafka;

   $ bin/kafka-topics.sh --list --zookeeper localhost:2181

3. To check the data is landing on kafka topic and to print it out;

   $ bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic your_topic_name --from-beginning

Answer 4

To read messages you should use:

kafka-console-consumer.sh --bootstrap-server kafka1:9092,kafka2:9092,kafka3:9092 --topic messages --from-beginning

--bootstrap-server is required attribute. You can use only single kafka1:9020 node.

Answer 5

Kafka uses ZooKeeper so you need to first start a ZooKeeper server if you don't already have one.

If you do not want to install and have a separate zookeeper server, you can use the convenience script packaged with kafka to get a quick-and-dirty single-node ZooKeeper instance.

Starting the single-node Zookeeper instance:

bin/zookeeper-server-start.sh config/zookeeper.properties

Starting the Kafka Server:

bin/kafka-server-start.sh config/server.properties

Listing the Topics available in Kafka:

bin/kafka-topics.sh --list --zookeeper localhost:2181

Answer 6

For dockerized kafka/zookeeper

docker ps

find you zookeeper container id

docker exec -it <id> bash

cd bin

./zkCli.sh

ls /brokers/topics
