Installing Kafka with Zookeeper

Tools Command Line tools

Hi,
Learning Kafka and need a little help with installing Zookeeper and Kafka on my Mac (V12.01)

I’ve installed Zookeeper from Brew
I’ve installed kafka from Brew.

Was trying to call the following command:

kafka-topics --create --topic rameTest --bootstrap-server 127.0.0.1:2181

and I get the following error:

ERROR org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment. Call: createTopics
 (kafka.admin.TopicCommand$)

Is there any configuration setting I need to do to kafka to link Zookeeper?

Thank you for the help

Hi @dramer

welcome to the forum :slight_smile:

some questions to better understand your starting point

  • did you check whether kafka and zookeeper are running?
  • did you check the logfiles of kafka and zookeeper?

best,
michael

Thank you so much for the help.

Once Zookeeper is installed it tells you how to start it…

To start zookeeper now and restart at login:

brew services start zookeeper

Or, if you don’t want/need a background service you can just run:

zkServer start

Davids-MacBook-Pro:~ davidramer$ zkServer start

ZooKeeper JMX enabled by default

Using config: /usr/local/etc/zookeeper/zoo.cfg

Starting zookeeper ... STARTED


 ps -rf | grep zookeeper
  501 64128 61231   0  3:18PM ttys000    0:00.00 grep zookeeper

then installed Kafka and restated it

Davids-MacBook-Pro:~ davidramer$ brew services restart kafka

Not sure where the log file is to review? can you point me to it?

thanks for the information

I guess there should be directory
like /usr/local/etc/kafka there should be a log4j conf (not sure if it’s there in homebrew installations but in vanilla kafka installation there is one :wink: )

btw just discovered that you’ve used the zookeeper default port to connect to the cluster

would you please try the following:
kafka-topics --create --topic rameTest --bootstrap-server 127.0.0.1:9092

hth,
michael
