Thanks Mikols for notifying on this. I think docker support is general known as alpha feature so document it as experimental is nice to have but not a blocker for 2.8.2. I also noticed that our 2.7.x document (https://hadoop.apache.org/docs/r2.7.4/hadoop-yarn/hadoop-yarn-site/DockerContainerExecutor.html) without mentioning docker support is experimental. We may need to fix that as well in following releases.
I can also add it (mentioning docker container support feature is experimental) to release message in public website just like previous release we call 2.7.0/2.8.0 as non-production release. I think vote should continue until we could find a real blocker.
