HADOOP-16494, artifacts generated for release doesn't include mds file. But hadoop web site binary tar ball points to mds file which doesn't have. This breaks the hadoop website.
For 3.2.1 release, I have manually generated mds file and pushed into artifacts folder so that hadoop website link is not broken.
The same issue will happen for 3.1.3 release also.
I am referring https://hadoop.apache.org/releases.html page for checksum hyperlink.
