That's just the Oracle 'commercial' JDK though. OpenJDK is still OSS and 8 is updated there too. Oracle JDK is still free too, just not for commercial use and commercial support for 8 (IIUC). I think that's the 'audience' here, and I don't know how large or small that is. That said a key first

So I'm not a lawyer, but looking at the JDK8 License FAQ ( https://www.oracle.com/technetwork/java/javase/overview/oracle-jdk-faqs.html ) makes me feel like we should support folks who are on the 2.x branch and want to migrate away from JDK8. Although the Redhat post about OpenJDK8 is reassuring (

Spark 3 will not require Java 11; it will work with Java 8 too. I think the question is whether someone who _wants_ Java 11 should have a 2.x release instead of 3.0. In practice... how much are people moving off Java 8 right now? It's still my default, because most but not all things work with

Not a contributor, but a user perspective… As Spark 3.x will be an evolution, I am not completely shocked that it would imply a Java 11 requirement as well. Would be great to have both Java 8 and Java 11, but one needs to be able to say goodbye. Java 8 is great, still using it actively in

I think one of the key problems here are the required dependency upgrades. It would mean many minor breaking changes and a few bigger ones, notably around Hive, and forces a scala 2.12-only update. I think my question is whether that even makes sense as a minor release? it wouldn't be backwards

Hello everyone, Thank you all for working on supporting JDK11 in Apache Spark 3.0 as a community. Java 8 is already end of life for commercial users, and many companies are moving to Java 11. The release date for Apache Spark 3.0 is still not there yet, and there are many API
