> hadoop's {{checknative}} command looks for native binaries and returns an error code
if one is missing.
> But it doesn't check for {{winutils.exe}} on windows, which turns out to be essential
for some operations. 
> Adding this check to the -a (or default) operation would allow the check to be used as
a health check on windows installations
