-------------------------------------
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}}.
