kafka Manager CMAK does not support java 8 anymore

Question

I am looking to install kafka Manager tool, I already have installed:

• Kafka version 3.1.0
• openjdk version "1.8.0_322"
• The Java_HOME is:

~ $ echo $JAVA_HOME /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.322.b06-11.el8.x86_64/jre

When I see official Yahoo Kafka Manager , it require Java 11+ https://github.com/yahoo/CMAK

But I have Java 8

I found an old git repository supporting Java 8: https://github.com/BonnierNews/kafka-manager

in the tuto, Again, if java is not in your path, or you need to run against a different version of java, using the following :

$ PATH=/usr/lib/jvm/zulu-11-amd64/bin:$PATH \
  JAVA_HOME=/usr/lib/jvm/zulu-11-amd64 \
  /path/to/sbt -java-home /usr/lib/jvm/zulu-11-amd64 clean dist

But is it that this cmd with change the java path and will affect the infrastructure installe ????

How is it possible to install kafka Manager ? is it ok if I install both java version?

Answer 1

You should definitely update Java.

Having both on your system is fine, but Java 8 will soon be end of life, and will not get security patches, potentially leaving your system to be vulnerable to exploits.

I would not recommend running old forks of CMAK only to workaround your need to use an older Java version

this cmd with change the java path and will affect the infrastructure installe ????

No. Those variables are only used for that sbt dist command

Alternative solution would be to run CMAK in Docker
