Summary: Kubernetes version support strategy on test nodes and for the backend Key: SPARK-26973 URL: https://issues.apache.org/jira/browse/SPARK-26973 Project: Spark Issue Type: Test Components: Kubernetes Affects Versions: 3.0.0 Reporter: Stavros Kontopoulos Kubernetes has a policy for supporting three minor releases and the current are defined here: [https://github.com/kubernetes/sig-release/blob/master/releases/patch-releases.md.|https://github.com/kubernetes/sig-release/blob/master/releases/patch-releases.md].] Moving from release 1.x to 1.(x+1) happens roughly every 100 days:[https://gravitational.com/blog/kubernetes-release-cycle.] This has an effect on dependencies upgrade at the Spark on K8s backend and the version of Minikube required to be supported for testing. One other issue is what the users actually want at the given time of a release. Some popular vendors like EKS([https://aws.amazon.com/eks/faqs/] have their own roadmap for releases. Follow the comments a recent discussion on the topic: [https://github.com/apache/spark/pull/23814.] Clearly we need a strategy for this. A couple of options for the current state of things: a) Support only the last two version, but that leaves out a version that still receives patches. b) Support only the latest, which makes testing easier, but leaves out other currently maintained version. A good strategy will optimize the following: 1) percentage of users satisfied at release time. 2) how long it takes to support the latest K8s version 3) testing requirements eg. minikube versions used -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
