Supported Java versions for running Talend artifacts with Talend Studio 8.0 R2025-02 and later
- 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 following table shows in which Java environments the corresponding item can be executed:
Java version for execution | Support type |
---|---|
17 | Supported Note that Routines compliance can be set up to Java 8 or 17. |
Java version for execution | Support type |

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