Try this:

{ 
   Configuration config = new Configuration();
   config.addResource(new Path("/etc/hadoop/conf/core-site.xml"));
   config.addResource(new Path("/etc/hadoop/conf/hdfs-site.xml"));

   config.set("fs.hdfs.impl", 
            org.apache.hadoop.hdfs.DistributedFileSystem.class.getName()
        );
       config.set("fs.file.impl",
            org.apache.hadoop.fs.LocalFileSystem.class.getName()
        );
  FileSystem dfs = FileSystem.get(config);
  String dirName = "TestDirectory";
  System.out.println(dfs.getWorkingDirectory() +" this is from /n/n");
  Path src = new Path(dfs.getWorkingDirectory()+"/"+dirName);

   dfs.mkdirs(src); 

} }
