Which java version is used here?

Hello,

We see that in the label that you are using Talend 8, However even with Talend 8 for Talend Server Modules Big Data Distribution the recommended Java version is version 8 as stated on this page:

https://help.talend.com/r/en-US/8.0/installation-guide-linux/compatible-java-environments

The error you reported is also covered in a KB article:

https://community.talend.com/s/article/Talend-Big-Data-compatibility-with-Zulu-OpenJDK-98ERC?languag...

And the solution proposed is to use JDK version 8.

Best regards

Hello,

To run your Spark Jobs and Standard Jobs or Metadata Repository that involve big data distributions, you need to install Java 8 on your computer, and in Talend Studio customize the path in Preferences > Talend > Java interpreter and then browse the location of JDK 8 in Preferences > Java > Installed JREs.

Don't forget to restart your studio to apply it.

Best regards

Sabrina
