[Condor-users] Inserting a filestagein element into a condor-g job

[Patrick Armstrong <patricka@xxxxxxx>]

I've been trying to figure out a way to stage some files from a gsiftp  
server to a Globus 4.0 resource in my condor pool. The way we've been  
doing this in the past is to first copy the files to the condor  
scheduler then stage them with transfer_input_files.

What I've been trying is to add the <filestagein> element to the  
classad with globus_xml. This seems like it should work in theory, but  
I've found that when I insert a filestagein element this way, Condor  
doesn't add the <transfercredentialendpoint> to the job description.  
eg, a filestagein element created by condor looks like this:

<ns1:fileStageIn>
<ns11:maxAttempts>5</ns11:maxAttempts>
<ns12:transferCredentialEndpoint>
<ns13:Address>
https://142.104.60.93:8443/wsrf/services/DelegationService
</ns13:Address>
<ns14:ReferenceProperties>
<ns1:DelegationKey>24178780-5768-11dd-8276-c722f12d4433</ 
ns1:DelegationKey>
</ns14:ReferenceProperties>
<ns15:ReferenceParameters/>
</ns12:transferCredentialEndpoint>
<ns16:transfer>
<ns16:sourceUrl>
gsiftp://ms-gavia.phys.uvic.ca/tmp/condor_g_empty_dir_u507/
</ns16:sourceUrl>
<ns16:destinationUrl>file:///${GLOBUS_SCRATCH_DIR}</ns16:destinationUrl>
</ns16:transfer>
...

And a filestagein I inject looks like this:
<ns1:fileStageIn>
<ns11:transfer>
<ns11:sourceUrl>
gsiftp://heplw26.phys.uvic.ca:2811/some/file
</ns11:sourceUrl>
<ns11:destinationUrl>file:///${GLOBUS_USER_HOME}/some/file</ 
ns11:destinationUrl>
</ns11:transfer>

The job seems to be failing on the globus resource because this isn't  
included.

Is there any way I can force Condor to add the  
transfercredentialendpoint? Or, alternately, is there a $$() macro  
that I can use to add this in manually?

Am I looking at this the wrong way? Is there a better way to submit a  
job that will stage from a gsiftp server?
