           Summary: indicate host gridftp server that caused the error:
           Product: Swift
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: error messages
        AssignedTo: skenny at uchicago.edu
        ReportedBy: aespinosa at cs.uchicago.edu
                CC: swift-devel at ci.uchicago.edu


type file;

app (file o) cat(file i) {
  cat i @stdout=o;
}

file y<"gsiftp://somehost//filename3">;
file x <"gsiftp://somehost//filename";

x=cat(y);

sites.xml

<config>
  <pool>
    ...
    ...
  <gridftp url="gsiftp://anotherhost"/>
  <workdirectory>/someworkdir</workdirectory>
  </pool>
</config>

When something goes wrong with either hosts 'somehost' and 'another' host, logs
and error messages only report this: 
...
Caused by: org.globus.cog.abstraction.impl.file.IrrecoverableResourceException:
Error communicating with the GridFTP server
Caused by: org.globus.cog.abstraction.impl.common.task.TaskSubmissionException:
org.globus.cog.abstraction.impl.file.IrrecoverableResourceException: Error
communicating with the GridFTP server
Caused by: org.globus.cog.abstraction.impl.file.IrrecoverableResourceException:
Error communicating with the GridFTP server
Caused by: java.net.ConnectException: Connection refused
Final status:  Failed:4  Finished in previous run:11

This is manageable for single remote resources. but with more pools (hence
gridftp endpoints), this is getting harder to debug
