             Summary: On Windows localized resources are not moved to the front of the classpath when they should be
                 Key: YARN-3626
                 URL: https://issues.apache.org/jira/browse/YARN-3626
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
         Environment: Windows
            Reporter: Craig Welch
            Assignee: Craig Welch


In response to the mapreduce.job.user.classpath.first setting the classpath is ordered differently so that localized resources will appear before system classpath resources when tasks execute.  On Windows this does not work because the localized resources are not linked into their final location when the classpath jar is created.  To compensate for that localized jar resources are added directly to the classpath generated for the jar rather than being discovered from the localized directories.  Unfortunately, they are always appended to the classpath, and so are never preferred over system resources.
