Question

I am getting an error while reading a topic from a single node cluster

kafka-console-producer.bat -- broker-list localhost:9092 -- topic raja

Error below

Missing required argument "[topic]"

kafka version-kafka_2.13-2.4.0

Answer 1

You've got a space between the parameter labels, so it won't work. Also note consumer not producer if you're reading from the topic.

Try:

kafka-console-consumer.bat --broker-list localhost:9092 --topic raja

Ref: https://kafka.apache.org/documentation/#quickstart_consume

Answer 2

I suggest you do more research and training.

You use kafka CONSUMER to read from a topic, NOT PRODUCER,
and also, as @Robin Moffatt mentioned while I was typing the answer,
remove spaces between the parameter labels:

kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic raja

This should work.

If you want to read the topic from the beginning then add this as well:

--from-beginning
