What’s the latest status on Java 17 runtime support for Hadoop? Do we have a roadmap when and what the next Hadoop release will support it?

In my opinion, upgrading is very beneficial. Based on the roadmap for Spark 4.0, we can see that JDK8/JDK11 is no longer the default version. Therefore, I believe it is important for us to fully support JDK11/JDK17/JDK21 in Hadoop. From the information I have gathered, we currently do not have full support for JDK11. I think it is necessary for us to address this issue first and gradually move towards supporting JDK17. I'd like to hear other members' opinions. I am willing to start this work to make hadoop support JDK11 and JDK17 after the release of hadoop-3.4.0. Before that, we need to hear the opinions of other team members.

It's true that we need to have pipelines for JDK17 builds, and it's good to see that some Jira’s are already in progress to support it. We may need to check with the infrastructure team as well. Does anyone else have any thoughts or concerns on this? It seems like this topic is not very active.

Can we have a new pipeline for jdk17 builds? I can see that all jira's under HADOOP-17177 which got merged are not run on jdk17 as of now. It would be helpful if we have dedicated pipeline. Thanks, Bilwa
