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 getting below error:

Error: Could not find or load main class org.apache.zookeeper.server.quorum.QuorumPeerMain

My environment is Windows 7 64 bit. I tried to follow below e-mail chain: Apache Email Chain . But still it's having same issue. Can anyone guide me in this? As I am very new to this and couldn't find many information on Google/Apache Kafka email chain.

Run these commands from your Kafka root folder:

cd bin\windows

Then run Zookeper server:

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

Then run Kafka server:

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

The gotcha here is to run the .bat files from the /bin/windows folder, so after you run your servers with the steps above and want to follow up with the tutorial, make sure you are running the correct batch files to create topics and whatnot, e.g.:

Create a topic:

kafka-topics.bat --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test

List topics:

kafka-topics.bat --list --zookeeper localhost:2181

I'm using kafka 0.10 without zookeeper. I want to get kafka topics list. This command is not working since we're not using zookeeper: bin/kafka-topics.sh --list --zookeeper localhost:2181. How can I get the same output without zookeeper?
