Compatible Java Environments

The following tables provide information on the recommended Java Environment to use with your Talend product from February 2025 and later. If you are using Talend 8.0 products that were not patched nor updated with the February 2025 updates or later ones, see Compatible Java Environment before February 2025.

The supported Java platforms are OpenJDK and Oracle JDK. The recommended distribution for OpenJDK is Zulu.

Information noteImportant: All Talend products and associated third-party applications, such as the Hadoop cluster, should use the same Java version for compliance. Before you install or upgrade any associated third-party application, Qlik recommends that you check which Java version they support.
Information noteTip: For more information about upgrading your modules and artifacts to use the latest supported Java version, see Using a more recent version of Java.

In the following documentation:

  • Recommended: designates an environment recommended by Qlik based on experience and customer usage.
  • Supported: designates a supported environment for use with the listed component or service.
  • Supported with limitations: designates an environment that is supported by Qlik but with certain conditions explained in notes.

1 To use Talend Administration Center with Java 17, you need to open the <tac_installation_folder>/apache-tomcat/bin/setenv.sh file and add the following commands:
# export modules 
export JAVA_OPTS="$JAVA_OPTS --add-opens=java.base/sun.security.x509=ALL-UNNAMED --add-opens=java.base/sun.security.pkcs=ALL-UNNAMED"
Information noteNote: The recommended Java environments for Big Data Distributions are OpenJDK 8 and Oracle JDK 8.

Supported Java versions for running Talend artifacts

All artifacts require Java 17 to build and execute in Talend Studio:
  • Data integration Jobs and Routes are compiled with Java 17.
  • Big Data Jobs are compiled with Java 8 with the add-opens parameters automatically included. Therefore, they can be executed with Java 17 in Talend modules, and with Java 8 in a big data cluster. In other words, the Job is launched with Java 17, then deployed in the cluster that runs in Java 8.
The Compiler Compliance Level corresponds to the Java version used for the Job code generation. For more information, see Setting up the Java version for Routines in Talend Studio.

The following table shows in which Java environments the corresponding item can be executed:

Supported Java versions to execute Data Integration Jobs
Java version for execution Support type
17 Supported

Note that Routines compliance can be set up to Java 8 or 17.

Supported Java versions to execute Routes and Data Services Jobs
Java version for execution Support type
17 Supported
Supported Java versions to execute Big Data Spark Jobs
Java version for execution Support type
17 Supported

Note that Routines compliance can be set up to Java 8 or 17.

The execution of the Big Data Spark Jobs actually depends on the Java versions supported by the cluster.
