Error creating Kafka Topics- Replication factor la

Question

I am trying to create topics in Kafka by following the guide on Apache Kafka website through command line. While running the command:

bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

I get the error as follows:

Error while executing topic command replication factor: 1 larger than available
brokers: 0
kafka.admin.AdminOperationException: replication factor: 1 larger than available

How can I resolve the issue? Any good documentation to get started with this? Thanks!!

Answer 1

I have had the same problem.I solve the problem.I think the reason for this is because there is no background start-up. so,we neet start-up background

bin/kafka-server-start.sh config/server.properties &
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test &

Seems like your server not started , check logs for issue

Kill process

sudo fuser -k 2181/tcp

run zookeeper

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

Run Kafka

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

I had the same problem but finally I tried the following steps which worked for me:

1)Create the chroot in the Zookeeper with the following commands:

zkCli.sh -server localhost:2181

create /kafka1 []

2)For the kafka brokers config , modify zookeeper.connect and add chroot path : For eg.

In server.properties :

zookeeper.connect=localhost:2181/kafka1

3)Start Zookeeper

4)Start Kafka Server

5) Create a topic as below: bin/kafka-topic.sh --create -zookeeper localhost:2181/kafka1 --replication-factor 1 --partitions 1 --topic data

6)Confirm the created topic: bin/kafka-topics.sh --list --zookeeper localhost:2181/kafka1

I followed below for reference: https://community.hortonworks.com/questions/102132/run-multiple-broker-versions-in-the-same-cluster.html
