    [ https://issues.apache.org/jira/browse/HADOOP-15941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16690136#comment-16690136 ] 

Uma Maheswara Rao G commented on HADOOP-15941:
----------------------------------------------

to make that package visible, we may need to add compiler Args with --add-exports

Adding the following snippet make things works.

in hadoop-project/pom.xml:

 

 

 

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-compiler-plugin</artifactId>
 <version>3.8.0</version>
 <configuration>
 <source>${javac.version}</source>
 <target>${javac.version}</target>
 <useIncrementalCompilation>false</useIncrementalCompilation>
 <!-- add flags to generate native headers -->
 <compilerArgs combine.children="append">
 <arg>-h</arg>
 <arg>${project.build.directory}/native/javah/</arg>
*<arg>--add-exports</arg>*
 *<arg>java.naming/com.sun.jndi.ldap=ALL-UNNAMED</arg>*
 </compilerArgs>
 </configuration>
 
 </plugin>
