Description

Some tests are unable to load the native DLL on Windows. The culprit appears to be an incorrect PATH configuration for the native-win profile in hadoop-project/pom.xml.

    <profile>
      <id>native-win</id>
      <activation>
        <os>
          <family>Windows</family>
        </os>
      </activation>
      <build>
        <plugins>
          <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
              <environmentVariables>
                <!-- Specify where to look for the native DLL on Windows -->
                <PATH>${env.PATH};${basedir}\..\..\hadoop-common-project\hadoop-common\target\bin;</PATH>
              </environmentVariables>
            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>

This is evaluated independently by each project and the relative path is not always correct.
