Andrew Wang commented on HADOOP-12055:
--------------------------------------

This function is only used in the one callsite I changed in the DN upgrade 
path. All our other hardlink usage already goes through HardLink which I 
believe does the OS abstraction. I haven't tested it though.

Do we think this is sufficient? Else, [~cnauroth] is this something you could 
help test? I don't have a Windows dev environment.

> Deprecate usage of NativeIO#link

> Since our min version is now JDK7, there's hardlink support via {{Files}}. 
> This means we can deprecate the JNI implementation and discontinue usage.
