It looks like there're something wrong in server side. Would you paste the relevant content
in core-site.xml in NN server?

I am trying to connect to my remote hadoop instance through a java client.

public static void main(String[] args) {
              try {
                     UserGroupInformation ugi = UserGroupInformation.createRemoteUser("vagrant");
                     ugi.doAs(new PrivilegedExceptionAction<Void>() {

                           public Void run() throws Exception {
                                  Configuration conf = new Configuration();
//                                conf.set("fs.defaultFS", "hdfs://");
                                  conf.set("hadoop.job.ugi", "vagrant");
                                  FileSystem fs = FileSystem.get(conf);
                                  fs.createNewFile(new Path("user/test/test-file"));
                                  FileStatus[] status = fs.listStatus(new Path("/user/test"));
                                  for(int i=0; i<status.length; i++)

                                  return null;
              } catch(Exception e) {

When I execute this I get the following exception.

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):
SIMPLE authentication is not enabled.  Available:[TOKEN]
       at org.apache.hadoop.ipc.Client.call(Client.java:1468)
       at org.apache.hadoop.ipc.Client.call(Client.java:1399)
       at org.apache.hadoop.ipc.ProtobufRpcEngine$Invoker.invoke(ProtobufRpcEngine.java:232)
       at com.sun.proxy.$Proxy9.getFileInfo(Unknown Source)

I have hadoop.security.authentication set to simple and hadoop.security.authorization set
to false in core-site.xml on my remote hadoop instance.  What am I doing wrong?  Any help
is much appreciated.

Best regards,
