> {{JniBasedUnixGroupsMapping}} calls native code which isn't implemented properly for
Windows, causing {{UnsatisfiedLinkError}}.  The fallback logic in {{JniBasedUnixGroupsMappingWithFallback}}
works by checking if the native code is loaded during startup.  In this case, hadoop.dll is
present and loaded, but it doesn't contain the right code.  There will be no attempt to fallback
to {{ShellBasedUnixGroupsMapping}}.
