-------------------------------------

             Summary: JniBasedUnixGroupsMappingWithFallback fails on Windows with UnsatisfiedLinkError
                 Key: HADOOP-9232
                 URL: https://issues.apache.org/jira/browse/HADOOP-9232
             Project: Hadoop Common
          Issue Type: Bug
          Components: native, security
    Affects Versions: trunk-win
            Reporter: Chris Nauroth


{{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}}.
