Issues faced while setting up Kafka on Windows OS and how I resolved it
Recently, I did a setup of Kafka on a Windows system and shared a Kafka guide to understand and learn. I was using a Win10 VM on my MacBook. It was not a breeze setup and had few hiccups on the way. It took some time for me to resolve them one after another looking around on web. Collating all of them here for quick reference.

ERROR #1

When

I tried to start Zookeeper.

Command

zookeeper-server-start.bat config\zookeeper.properties

Error

java.lang.IllegalArgumentException: config/zookeeper.properties file is missing

Stack Trace

INFO Reading configuration from: config/zookeeper.properties

How I Solved?

It was clearly the case of relative path. config/zookeeper.properties was at two roots lower than where the start up script was. Either I had to correct the level or use an absolute path to move ahead.

zookeeper-server-start.bat C:\Installs\kafka_2.12-2.5.0\config\zookeeper.properties
rem OR relative path option below

zookeeper-server-start.bat ../../config/zookeeper.properties

ERROR #2

When

Zookeeper is up and running. Attempted to start Kafka server and it failed.

Command

kafka-server-start.bat C:\Installs\kafka_2.12-2.5.0\config\server.properties

Error

How I Solved?

Investigation lead to increasing the timeout settings for Kafka-Zookeeper. Because of environment settings (RAM, CPU, etc), it turns out this plays some role.
I updated the ${kafka_home}/config/server.properties file:

# Timeout in ms for connecting to zookeeper (default it was 18000)
zookeeper.connection.timeout.ms=36000 

I read many other reasons for this error (did not look applicable to my case) like:

  1. zookeeper service not running
  2. restarting system
  3. zookeeper is hosted on zookeeper:2181 or other server name instead of localhost:2181

ERROR #3

Zookeeper is up and running. Attempted to start Kafka server and it failed.

How I Solved?

It turned out related to Java heap size. I made a change in the Kafka startup script file: ${kafka_home}/bin/windows/kafka-server-start.bat

IF NOT ERRORLEVEL 1 (
        rem 32-bit OS
        set KAFKA_HEAP_OPTS=-Xmx512M -Xms512M
    ) ELSE (
        rem 64-bit OS
        rem set KAFKA_HEAP_OPTS=-Xmx1G -Xms1G => Commented this
        rem added this below line
	set KAFKA_HEAP_OPTS=-Xmx512M -Xms512M
    )

Though, while looking for solution, quite a few also solved it up upgrading their Java from 32bit to 64bit application. I did not try this solution as had other Java setup dependencies on my system that I wanted to keep intact.

ERROR #4

When

I tried to delete Kafka topic because I was having problems while pushing message from Producer.

Command

kafka-topics.bat --list --bootstrap-server localhost:9092 --delete --topic my_topic_name

Error

Topic test is already marked for deletion

Stack Trace

Topic test is marked for deletion.
Note: This will have no impact if delete.topic.enable is not set to true.

How I Solved?

I enabled topic deletion configuration. It needs to be set as delete.topic.enable = true in file ${kafka_home}/config/server.properties. Restarted the server post updating the config.

# Delete topic enabled
delete.topic.enable=true

ERROR #5

When

Zookeeper & Kafka is up and running. I get an error when I try to create a Topic.

Command

kafka-topics.bat --create --bootstrap-server localhost:9092 
--replication-factor 1 --partitions 1 --topic testkafka

Error

How I Solved?

For once, it worked for me as is but when I tried again later, I kept getting this error. While looking on the web, suggestions were to enable listener and set it up like: listeners=PLAINTEXT://localhost:9093 in the server config file.

Before attempting this, I rebooted my system as it was little sluggish too. Turns out, mostly it was memory issue. I was in a Windows VM and probably it was craving for memory space. Without a change, things worked fine as is for me.

ERROR #6

When

This was during another instance of Kafka setup (from start) in a few days. Zookeeper is up and running. Attempted to start Kafka server and it failed.

Command

kafka-server-start.bat C:\Installs\kafka_2.12-2.5.0\config\server.properties

Error

It was around logs or lock file.

How I Solved?

Looking at details, it hinted me to look into pre-existing (something related to my previous setup). I went ahead and deleted the logs and data folder that was auto created when I moved ahead with the entire process setup. Post this, the error was gone. Believe my server shutdown was not smooth and thus something was interfering with the current startup.

Hope these would help. Keep learning!
