Unable to start Zookeeper server - Kafka Setup

Question

I am trying to setup Kafka referring to the quick start guide on the apache kafka page and while starting the zookeeper server it gets stuck at this step...Would appreciate if someone can help guide me through on how to start the zookeeper server

what script did you run? Have you written: bin/zookeeper-server-start.sh config/zookeeper.properties? – Massif

Answer 1

The terminal getting stuck at that step actually means that the server is running. So, while you may have thought you were getting an error, it actually means that the server has started.

I'm running through the same setup. Since you've opened the port in that terminal, you can proceed with the rest of the instructions from another terminal. You'll have to open multiple terminals throughout the setup, and eventually will be entering messages in one terminal (the producer), and seeing them appear in another terminal (the consumer).

My logs were stuck at this line, meaning zookeper could not start properly. I could not start kafka too.

0.0.0.0 might mean something is wrong, sometimes. I renewed my DHCP lease on my mac and (system preferences -> Advanced -> TCP/IP -> Renew DHCP lease), restarted zookeeper and it started working.

based on the screenshot posted, below line tells that zookeeper is running on the port 2181

it seems like you have started the zookeeper server successfully but without running the Kafka server you are trying to run Kafka commands and because of you are getting an error of broker is not available.

in mac run the following two commands in two tabs: start-zookeeper:

zookeeper-start-server /usr/local/kafka/zookeeper.properties

start kafka server:

kafka-server-start /usr/local/etc/kafka/server.properties

open another terminal and try out the Kafka commands, commands will run without any issues
