Doc Type: Bug Fix
Doc Text:
Cause The Aviary web service requires command arguments for all jobs submitted in cumin via Aviary. Cumin does not supply a command arguments value to Aviary if the user does not specify arguments. This is a problem for commands that take no arguments. Consequence Submissions that specify commands without arguments will be rejected with an error. This applies to regular submissions and VM submissions. Fix: Cumin supplies a null command arguments value to Aviary when no command arguments are specified by the user. Result It is possible to successfully submit commands with no arguments as jobs from cumin.

Description of problem:
  I'm not able to submit VM job from cumin via aviary. Submitting ends with:
    Submit VM job 'VM cumin job': Failed ('Args')
  And in web.log is following error:
    29483 2012-08-15 11:38:25,803 ERROR 'Args'
    Traceback (most recent call last):
      File "/usr/share/cumin/python/cumin/task.py", line 98, in invoke
        self.do_invoke(session, obj, invoc, *args, **kwargs)
      File "/usr/share/cumin/python/cumin/grid/submission.py", line 720, in do_invoke
      File "/usr/share/cumin/python/sage/aviary/aviaryoperations.py", line 152, in submit_job
    KeyError: 'Args'

Version-Release number of selected component (if applicable):

# rpm -qa | grep -e cumin -e condor

How reproducible:

Steps to Reproduce:
1. Install and configure cumin to connect to condor pool with VM universe configured (via aviary).
2. Try to submit VM job via cumin (I filled only description and vm image location).
Actual results:
  Submission failed with following error and error message in web.log:
    Submit VM job 'VM cumin job': Failed ('Args')

Expected results:
  Job is correctly submitted and no error appear.

Comment 1 Trevor McKay 2012-08-15 09:50:14 EDT
This is actually a general problem, not specific to VM jobs.

The same failure can be seen when submitting a normal job with no command arguments ("/bin/sleep" in the command field rather than "/bin/sleep 1d")

Comment 8 Trevor McKay 2012-08-16 13:02:51 EDT
Setting needinfo on dahorak.

Daniel, I think I've found a workaround.  Please confirm.

  If you expand the form for a regular submission or a VM submission and add a blank Args field in extra attributes, it will work.  

Extra attributes should look like this, with nothing after the =:

Args =

 This should get the job out of Cumin, and it will not be passed any arguments when it runs.

I checked this workaround and it is working.

    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.
    New Contents:
    The CuminAviary Tech Preview feature requires command arguments for jobs submitted in Cumin via Aviary.

    Submissions that specify commands without arguments will be rejected by Cumin with an error.  This applies to regular submissions and VM submissions.

    Expand the submission form via the "Show more" button and add the string "Args =" to the "Extra attributes" field. This will satisfy the restriction in Cumin without defining any actual arguments.  The job will run in condor without any arguments being passed to the command.

    This workaround should be 100% effective for submitting jobs without command arguments via Aviary.
Comment 13 Trevor McKay 2012-08-16 15:34:57 EDT
This is fixed in revision 5445 on trunk
Comment 14 Trevor McKay 2012-10-03 16:08:08 EDT

This can be done with a simple (non-vm) job since this is a general problem in the aviaryoperations code

1) Choose a command that legitimately takes no arguments.  I used /bin/date.

2) Create a simple submission with "Submit job"

3) This command will run very quickly, and may not even be visible in condor_q to verify that it's running. So, click the "Show more" button and set "Standard output" to "/tmp/mytest".  You may also set "Standard error" and "User Log" to files in /tmp.

4) Submit the job.  It should go "Pending" and then "OK"

5) Check /tmp/mytest for output.  In the case of /bin/date, there should be a date string in the file to confirm that the command ran.
Comment 16 Daniel Horák 2013-01-28 07:29:20 EST
I seems like there is some new problem - the logs and messages are different, but it still don't work.

Submitting job without arguments leads to error message in cumin:
  2013-01-28 13:21:09  Submit job 'Job without arguments 2': Failed (Operation failed on host HOSTNAME, (u"Server raised fault: 'Data element of the OM Node is NULL'",))

Behaviour for VM universe job is similar.
Workaround for MRG 2.2. from comment 8 works well.

Comment 17 Trevor McKay 2013-01-28 10:52:50 EST
My fix for this issue is incorrect.

Instead of an exception occurring in cumin, badly constructed messsages are being passed to Aviary and the server is raising an exception.  So the error is different but overall result is the same.

Summary of current status: this is a known issue since 2.1, it is still broken, and there is a known workaround.

Retested and verified on RHEL 5.9/6.4 - i386/x86_64.
