Zookeeper/Kafka not starting

[Andrew Smith]

Looking for info on how to run Kafka on IBM i - have downloaded 2.13-2.6.0 directly and extracted it.

Running from Bash on V7R3 with TL19311 installed

OpenSource environment updated and latest Java group PTF

Attempting to start Zookeeper using :

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

from the base directory for kafka_2.13-2.6.0 gives an error from the JVM - stating

The Kafka files were scp:ed from an AIX LPAR having downloaded them first and unzipped.

OpenSource environment is up to date and appears to work.

Looking really for guidance rather than a bug tbh. Any help/assistance gratefully received

Hi Andrew,

Could you try openjdk-11 (installed with yum and then set JAVA_HOME=/QOpenSys/pkgs/lib/jvm/openjdk-11)?

[Andrew Smith]

Thanks for the reply Eric, I will give it a go and see what it does.

Currently it is trying with the regular IBM supplied 64-bit version 8, so it is definitely worth a try.

‌

I’ll post here with how it goes.

@Eric - tested that with the OpenJDK instead and it works perfectly! Thank you very much for your help, it is very much appreciated.
