Apache Kafka error on windows - Couldnot find or load main class QuorumPeerMain

Question

I just downloaded Kafka 2.8.0 from Apache website, and I am trying to setup using the instructions given on the website. But when I try to start zookeper server, I am gettin

Answer 1

The solution for windows OS is to do the following:

1. Download the binary version instead of the source version from the official website of Apache Kafka.
2. Make sure the JAVA_HOME environment variable does not have a space in it (by default it is installed in Program files), follow the official installation documentation for this. https://docs.oracle.com/cd/E39271_01/general.300/eid_getting_started/src/tgs_install_jdk.html.
3. Make sure the JRE path and KAFKA_HOME path do not have spaces in them as well.
4. Run the zookeeper before starting Kafka.

Answer 2

I am using below mention command in windows environment.

Confluent_home\bin\windows> zookeeper-server-start.bat ..\..\etc\kafka\zookeeper.properties

if still you are getting the same error, then please verify you folder structure, Is there any space between folder name if yes then replace with either "_" or removed completely.

I was also facing the same error.

Answer 3

First Thing: Remove all blank space from the folder name. Second Thing: Use Powershell

Wrong Path:

d:\kafka node> .\bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

Correct Path

d:\kafka_node> .\bin\windows\zookeeper-server-start.bat .\config\zookeeper.properties

Answer 4

Had the same error message even though I had the correct Kafka download for my Scala version.

It ended up I was running the non-windows sh file (needed to run the bat in the windows sub-folder) and was running from within the bin folder instead of the root. Moving up to the root Kafka folder and running from there appears to have worked.

C:\kafka_2.10-0.8.2.0>bin\windows\zookeeper-server-start.bat config\zookeeper.properties

Answer 5

I used to meet the issue by running below cmd via git bash tool.

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

Solution: I switched to cygwin tool (http://cygwin.com/) to run the same cmd and I did not see the issue any more.

Answer 6

Its bit weird. But replacing the root folder name to Kafka resolved my issue. It might help one or others.
