Kafka - Confluent - Java Version Support

Question

I am looking at Apache Kafka v2.0.0 and I can\'t figure out what version of java it supports (OpenJDK or Oracle JDK\'s new lifecycle)? So far I have seen conflicting documentati

Answer 1

Apache Kafka v2.0.0

Apache Kafka official documentation is quite clear on that:

From a security perspective, we recommend you use the latest released version of JDK 1.8 as older freely available versions have disclosed security vulnerabilities. LinkedIn is currently running JDK 1.8 u5 (looking to upgrade to a newer version) with the G1 collector.

Also, notable changes in 2.0.0 section mentions the following:

Support for Java 7 has been dropped, Java 8 is now the minimum version required.

Oracle JDK is recommended but openJDK or Zulu should work fine for most cases as well.

Confluent Platform 5.0.x

For Confluent Kafka in particular,

Java 1.9 and 1.10 are not currently supported in Confluent Platform. Later versions of Confluent Platform will support these Java versions.

and the minimum recommended version for Confluent 5.0.x (that comes with Kafka v2.0.0) is JDK 1.8 → u31 or later.
