Change WorkDirectory with Job Submission Filter

  Dear all,

  Currently I am trying to use Job Submission Filter to change the WorkDirectory of a job, but I have not been able to make it to work successfully.

  The reason why I am doing this is because I want force each job to use the correct (internal hostname) work directory path.

  For example,

  "\\FileServer\\share" is the path that users use to access the file server from a client machine.

  "\\LocalFS\\share" is the path (private network) used inside the cluster.

  So, if a job's work directory contains "\\FileServer\", I want to convert it to "\\LocalFS\" by using job submission filter.

  I have posted the C# code below.

  I have used File.Copy to copy the xml file to make sure the change has been made, and it seems like the path in the xml file had been modified successfully,

  but the path in the job remains unchanged.

  Changing job priority worked with out problem.

  Could someone tell me if I am doing something wrong, or maybe changing WorkDirectory is not supported?

   XmlDocument xml = new XmlDocument();  
   XmlAttributeCollection attributes, attributes2;
    
   xml.Load(args[0]);
          XmlNamespaceManager nsMgr = new XmlNamespaceManager(xml.NameTable);
          nsMgr.AddNamespace("hpc", "http://schemas.microsoft.com/HPCS2008R2/scheduler/");
  
          XmlNode job = null;
          XmlNode job2 = null;
          
          job = xml.SelectSingleNode("/hpc:Job",nsMgr);        
  
          foreach (XmlNode temp in job.ChildNodes)
            if (temp.Name == "Tasks")
            {
              job2 = temp.ChildNodes[0];
              break;
            }
  
          attributes = job.Attributes;
          attributes2 = job2.Attributes;
  
          attributes["Priority"].Value = JobPriority.Highest.ToString();
  
          File.Copy(args[0], "D:\\temp\\org.xml", true);
          attributes2["WorkDirectory"].Value = "\\\\Machine1\\Share"; //Forceing WorkDirectory to \\Machine1\\Share just for testing.
          xml.Save(args[0]);
          File.Copy(args[0], "D:\\temp\\moded.xml", true);
          
          return 1;
  
  

  By the way, is there a easier way to access the attributes of "Tasks" other than using foreach loop?

          foreach (XmlNode temp in job.ChildNodes)
            if (temp.Name == "Tasks")
            {
              job2 = temp.ChildNodes[0];
              break;
            }
  

  Thank you.
