At first we thought it could be an ssh issue but submitting jobs and getting the output back isn't a problem when I do it from my personal user manually, so it's really related to Galaxy. We're using PBS Pro btw.

And I'm still at loss... :(

I am having the same problem when I use condor as the scheduler instead of sge.

发件人: Louise-Amélie Schmitt<louise-amelie.schmitt@embl.de> 主题: [galaxy-dev] Error: Job output not returned from cluster 收件人: galaxy-dev@lists.bx.psu.edu 日期: 2012年4月23日,周一,下午5:09 Hello everyone,

I'm still trying to set up the job submission as the real user, and I get a mysterious error. The job obviously runs somewhere and when it ends it is in error state and displays the following message: "Job output not returned from cluster"

In the Galaxy log I have the following lines when the job finishes running:

galaxy.jobs.runners.drmaa DEBUG 2012-04-23 10:36:41,509 (1455/9161620.pbs-master2.embl.de) state change: job finished, but failed galaxy.jobs.runners.drmaa DEBUG 2012-04-23 10:36:41,511 Job output not returned from cluster galaxy.jobs DEBUG 2012-04-23 10:36:41,547 finish(): Moved /g/funcgen/galaxy-dev/database/job_working_directory/001/1455/galaxy_dataset_2441.dat

The /g/funcgen/galaxy-dev/database/job_working_directory/001/1455/ directory is empty and /g/funcgen/galaxy-dev/database/files/002/dataset_2441.dat exists but is empty.

Any ideas about what can go wrong there? Any lead would be immensely appreciated!

Thanks, L-A

I run Galaxy as real user on our cluster with pbs (free version). We first configure LDAP authentification for having email account related to unix account (just cut the @curie.fr) Then I have modify pbs.py (in <GALAXY_DIR>galaxy-dist/lib/galaxy/jobs/runners) I have just disconnected the pbs submission through python library and replace it by a system call (just like I send jobs to the cluster with command line), here is the code used: galaxy_job_id = job_wrapper.job_id log.debug("(%s) submitting file %s" % ( galaxy_job_id, job_file ) ) log.debug("(%s) command is: %s" % ( galaxy_job_id, command_line ) ) # Submit job with system call instead of using python PBS library - Permit to run jobs as .. with sudo -u cmd prefix galaxy_job_idSTR = str(job_wrapper.job_id) galaxy_tool_idSTR = str(job_wrapper.tool.id) galaxy_job_name = galaxy_job_idSTR+"_"+galaxy_tool_idSTR+"_"+job_wrapper.user torque_options = runner_url.split("/") queue = torque_options[3] ressources = torque_options[4] user_mail = job_wrapper.user.split("@") username = user_mail[0] torque_cmd = "sudo -u username echo "+"\""+command_line+"\" | qsub -o "+ofile+" -e "+efile+" -M "+job_wrapper.user+" -N "+galaxy_job_name+" -q "+queue+" "+ressources submit_pbs_job = os.popen(torque_cmd) job_id = submit_pbs_job.read().rstrip("\n") #Original job launcher #job_id = pbs.pbs_submit(c, job_attrs, job_file, pbs_queue_name, None) pbs.pbs_disconnect(c) Second thing I have done is to wait error and output file from torque in the finish_job function (if not, I never receive the output, seems to be your problem..), here is the code used: def finish_job( self, pbs_job_state ): """ Get the output/error for a finished job, pass to `job_wrapper.finish` and cleanup all the PBS temporary files.

Hi,

Thanks a lot it actually helped. It is not exactly as straightforward in drmaa.py but somehow I could manage.

However, it was not the problem. For some reason, the user needs to write files from the node to job_working_directory/00X/XXXX/ and the latter is not world-writable. I had to make everyone chmod everything to 777 to make it work. Did I miss something?

That doesn't seem right. The subdirectory for your job underneath job_working_directory/00X/XXX/ should be chowned to the real user before the job is submitted and then chowned back to the galaxy user once the job is complete. --nate

Best, L-A

Hi L-A,

I run Galaxy as real user on our cluster with pbs (free version).

We first configure LDAP authentification for having email account related to unix account (just cut the @curie.fr) Then I have modify pbs.py (in <GALAXY_DIR>galaxy-dist/lib/galaxy/jobs/runners)

I have just disconnected the pbs submission through python library and replace it by a system call (just like I send jobs to the cluster with command line), here is the code used:

galaxy_job_id = job_wrapper.job_id log.debug("(%s) submitting file %s" % ( galaxy_job_id, job_file ) ) log.debug("(%s) command is: %s" % ( galaxy_job_id, command_line ) )

# Submit job with system call instead of using python PBS library - Permit to run jobs as .. with sudo -u cmd prefix

galaxy_job_idSTR = str(job_wrapper.job_id) galaxy_tool_idSTR = str(job_wrapper.tool.id) galaxy_job_name = galaxy_job_idSTR+"_"+galaxy_tool_idSTR+"_"+job_wrapper.user torque_options = runner_url.split("/") queue = torque_options[3] ressources = torque_options[4] user_mail = job_wrapper.user.split("@") username = user_mail[0]

torque_cmd = "sudo -u username echo "+"\""+command_line+"\" | qsub -o "+ofile+" -e "+efile+" -M "+job_wrapper.user+" -N "+galaxy_job_name+" -q "+queue+" "+ressources

submit_pbs_job = os.popen(torque_cmd)

job_id = submit_pbs_job.read().rstrip("\n")

#Original job launcher #job_id = pbs.pbs_submit(c, job_attrs, job_file, pbs_queue_name, None)

pbs.pbs_disconnect(c)

Second thing I have done is to wait error and output file from torque in the finish_job function (if not, I never receive the output, seems to be your problem..), here is the code used:

def finish_job( self, pbs_job_state ): """ Get the output/error for a finished job, pass to `job_wrapper.finish` and cleanup all the PBS temporary files. """ ofile = pbs_job_state.ofile efile = pbs_job_state.efile job_file = pbs_job_state.job_file

# collect the output try:

# With qsub system call, need to wait efile and ofile creation at the end of the job execution before reading them

efileExists = os.path.isfile(efile) ofileExists = os.path.isfile(ofile) efileExistsSTR = str(efileExists) ofileExistsSTR = str(ofileExists)

while efileExistsSTR == "False": time.sleep( 1 ) efileExists = os.path.isfile(efile) efileExistsSTR = str(efileExists)

while ofileExistsSTR == "False": time.sleep( 1 ) ofileExists = os.path.isfile(ofile) ofileExistsSTR = str(ofileExists)

# Back to original code

ofh = file(ofile, "r") efh = file(efile, "r") stdout = ofh.read( 32768 ) stderr = efh.read( 32768 ) except: stdout = '' stderr = 'Job output not returned by PBS: the output datasets were deleted while the job was running, the job was manually dequeued or there was a cluster error.' log.debug(stderr)

* Last step is to allow galaxy user to run sudo

Hope it can help you finding your problem..

See you,

Alban
