Hadoop contributions are coming from many places, so I don't see why this is
so important to know how close a particular distro will be to this a that ASF
release. Just the other day we had this long thread about contributions on
Hadoop general@ - it might be interesting to re-read it.

Perhaps I am missing the point of this discussion, but according to Hadoop
bylaws (available to anyone from https://hadoop.apache.org/bylaws.html):
When a release of one of the project's products is ready, a vote is required
to accept the release as an official release of the project.
Lazy Majority of active PMC members
What anything in this thread has to do with the quote above? Hadoop is
released when it is ready and a release is official by the lazy majority.
If downstream projects decide not to participate in support a release - well,
this is sad, but this happens. And this means that a particular release will
have a somewhat smaller stack available to our users.
