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. If it doesn't impact runtime, then is it still a problem for you? I can imagine it might still be an impact if you need to make a custom patched build from source. We do have some prior established policies for this sort of thing: https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Compatibility.html#Hardware.2FSoftware_Requirements "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." There is nothing in the phrasing about specific Linux distros, but I think if we were to follow the strictest interpretation, then the 3.4 release line would continue to work for the same OS distros. I understand the other way forward is to look for a gRPC compiler version that works on CentOS 7 and is also compatible with the Netty upgrade. Has there been any investigation into that?
