Subject I need help talking to HDFS over a firewall
Date Sat, 24 Sep 2011 00:19:06 GMT
   I have a small piece of code which opens hdfs. When I run the code my a
machine riunning Windows 7 from work it connects perfectly

String host = "myhost"
  int port = 9000;

 String connectString =   "hdfs://" + host + ":" + port + "/";
Configuration config = new Configuration();
            m_DFS = FileSystem.get(config);

When I run over a VPN from home it used to work but has stopped . The Hadoop
cluster at work may have been reconfigured

My windows firewall is turned off
telnet myhost 9000 works from the command line
 shows me the contents of HDFS

Our IT department insists is a firewall of some issue on my end. They also
insist that once I am connected through the VPN nothing is blocked on their

Is there any way this could be a cluster or hadoop issue. Again all of my
code talking to the cluster runs fine at work and nothing works from home
