WebHDFS ConnectionException: Connection refused

[Kyunam Kim]

HDFS is running on OS X and this simple app runs fine on the same OS X.

But if I move this jar to a Windows machine and run it there, I get into 
ConnectionException.

I can browse http://OSXMachine:50<http://.....:500570>070/ from Windows machine 
fine.

hadoop-2.6.4 is used with Oracle JDK 1.8.0_92.


public static void main(String[] args) throws IOException, 
InterruptedException, URISyntaxException {?

    Configuration conf = new Configuration();
    FileSystem fs = FileSystem.get(new URI("webhdfs://kyunam.esri.com:50070"), 
conf, "you");

    fs.mkdirs(new Path("TEST1"));
    fs.createNewFile(new Path("TEST2/test.txt"));   // <-- fails here
  }

Any help is appreciated.
