Invalid Config, Exiting abnormally when launching zookeper from Kafka tutorial

Question

I'm following this tutorial trying to set up kafka,

https://kafka.apache.org/quickstart

And I get this error when doing the part on zookeeper. It certainly has something to do with the config, but I don't understand to what extend.

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

Use fully qualified name if you are on windows. I was facing same issue but it was resolved when I used fully qualified path for batch file & properties file. – Phlox

Answer 1

If you look closely, you'll notice that the command to start Zookeeper is:

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

Using the zookeeper.properties file.

It looks like you copied the command to start Kafka which is using server.properties.

Smallish

I do not understand why they use this command if the good one is the one you wrote. It works with your command. Thanks a lot – Quartermaster

Answer 2

I fixed this on Windows by doing below.

Make sure to specify full paths.

First, go to the bin\windows folder of your kafka installation:

C:\kafka_2.12-2.0.0\bin\windows

Then, run the following command:

.\zookeeper-server-start.bat C:\kafka_2.12-2.0.0\config\zookeeper.properties

When done, you will see the following output:

[2020-07-06 20:25:13,703] INFO Server environment:user.dir=C:\kafka_2.12-2.0.0\bin\windows (org.apache.zookeeper.server.ZooKeeperServer)

Answer 3

You are using following to start the zookeeper:

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

Zookeeper configuration settings are placed in zookeeper.properties file. So, to start zookeeper:

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

And for starting KAFKA server:

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

Keep in mind which file comes with which server.

Answer 4

I am facing same issue because I am directly giving step2 command in my terminal,which is wrong. We have to run command of step2 in our Kafka folder. Follow below steps to run zookeeper successfully.

Step1: Goto your kafka folder or simply do cd $KAFKA_HOME

STEP2: bin/zookeeper-server-start.sh ./config/zookeeper.properties

1. check for "dataDir=/tmp/zookeeper1", if not present then create a directory and one file inside this directory myid

mkdir -p /tmp/zookeeper1
chmod -R 777 /tmp/zookeeper1
vi /tmp/zookeeper1/myid 
(add value as 1, this is server-id from server.1=)  

Jule

Hi, I tried to change dataDir from "/tmp/zookeeper" to "/var/lib/zookeeper" which contains a file called myid (didn't alter the text inside though) but the Zookeeper service failed to start with the same error described in the question. What could be wrong? – Portamento

Answer 6

On Window 10, this command solved this issue for me:

C:\kafka_2.13-3.6.0\bin\windows>zookeeper-server-start.bat C:\kafka_2.13-3.6.0\config\zookeeper.properties

Answer 7

I resolved it by the following steps,

export KAFKA_HOME=/home/kafka/kafka_2.13-3.7.0/
cd $KAFKA_HOME
bin/zookeeper-server-start.sh config/zookeeper.properties
bin/kafka-server-start.sh config/server.properties

Answer 8

I made a spelling mistake of "bin/zookeeper-server-start.sh config/zookeeper.propertie" missing the last character "s", the correct one should be: "bin/zookeeper-server-start.sh config/zookeeper.properties" wish i'll never be this dumb again..

Answer 9

Try to remove config/ , and use the file directly.

e.g.

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