Thank you very much for your suggestions! I will continue to improve the RC0 version.

The top page of site documentation (in hadoop-3.4.0-RC0-site.tar.gz) looks the same as 3.3.5. While the index.md.vm is updated in branch-3.4.0[1], it seems not to be reflected. release-3.4.0-RC0 tag should be pushed to make checking easier. In addition, the description about new features of previous release should be removed from the index.md.vm.
