"Support for any OS SHOULD NOT be dropped without first being documented as deprecated for a full major release and MUST NOT be dropped without first being deprecated for at least a full minor release."
I am not aware of any distro being explicitly deprecated by Hadoop, I don't think that the intent was for OS to be interpreted as distro. Especially the major release suggestion would be absurd, as it would suggest supporting distros for 15+ years. I've submitted a PR for reverting the plugin version in 3.4, but I still think that build support for Centos 7 should be dropped for 3.5. https://github.com/apache/hadoop/pull/7499 BTW the Centos 7 Docker image cannot even be built on 3.4, and no-one has complained in several months (it was only fixed on trunk) Istvan On Wed, Mar 12, 2025 at 12:17 AM Chris Nauroth <cnaur...@apache.org> wrote: > I'm adding Cheng Pan, who expressed concerns here: > > https://github.com/apache/hadoop/pull/7493#issuecomment-2710815286 > > Cheng, this is a build time issue.
