Subject: Example log files where glideins are blind to errors

Hi all.

Attached is the output of one glidein that failed to successfuly start a single user job,
yet the "parsed summary" reports 100% success rate!

Can someone fix it?
At least for this use-case?

I did the following experiment in order to check if our current code (mainly
can handle a situation similar to the one described in the ticket.

Each of the following 6 jdf files contains a different integer which will be the status return code

condor_submit test-0.jdf
condor_submit test-1.jdf
condor_submit test-2.jdf
condor_submit test-3.jdf
condor_submit test-4.jdf
condor_submit test-5.jdf

[hyunwoo@fermicloud159 ~]$ cat test-0.jdf
executable =
arguments = 0
universe = vanilla
output = test0.out
error = test0.error
log = test0.log

[hyunwoo@fermicloud159 ~]$ cat
import sys
import time

def main(argv=None):
return int(argv)

if name == "__main__":
print sys.argv
sys.exit( main(sys.argv1) )

Then, configured my Frontend to allow only one glidein

In fermicloud159:/etc/gwms-frontend/frontend.xml
<running_glideins_total curb="90000" max="1"/>
so that there is only one

[root@fermicloud158 ~]# condor_q g
Schedd: : <>
5912.0 frontend 10/9 11:27 0+00:13:36 R 0 0.1

So, all these 6 jobs went to one glidein
which can be seen in fermicloud025 whcih is the CE to which my Factory will deploy glideins:

[root@fermicloud025 tmp]# grep "Process exited" glide_08OiAZ/log/StarterLog
10/09/15 11:32:09 (pid:22xxx) Process exited, pid=22xxx, status=0
10/09/15 11:32:09 (pid:22xxy) Process exited, pid=22xxy, status=1
10/09/15 11:32:09 (pid:22092) Process exited, pid=22096, status=2
10/09/15 11:32:42 (pid:22117) Process exited, pid=22121, status=3
10/09/15 11:33:59 (pid:22176) Process exited, pid=22283, status=4
10/09/15 11:34:31 (pid:22297) Process exited, pid=22301, status=5

And finally I look at job.5912.0.out as follows
[root@fermicloud158 entry_ITB_FC_CE2]# less /var/log/gwms-factory/client/user_frontend/glidein_gfactory_instance/entry_ITB_FC_CE2/job.5912.0.out
This shows a correct percentage now..

Total badSignal jobs 0 (0%) utilization 0 (0%)
Total badOther jobs 0 (0%) utilization 0 (0%) === End Stats of main ===

It turns out our code is ok..

So, our guess about the situation under which the user observed his job.xxxx.0.out
is as follows:
Each of the series of jobs that went into the same glidein must be a wrapper which wraps a real job.
Looks like the wrapper script returned 0 regardless of the return code of the real job wrapped inside.
And judging from the fact that all jobs lasted only 30 seconds or so, the wrapped real jobs did not run successfully..

I also compared the format of the condor messages in StarterLog with the format described
in the current parsing_starterlog.awk which is the one that actually parses StarterLog.
They are same, namely, we can exclude the assumption that parsing_starterlog.awk might need some changing
due to a possibility of condor message format change.

I need to point out one more :

job.2284914.1.out shows

=== Stats of main ===
08/01/14 08:34:47 Starting job 543367.0 from
08/01/14 08:35:18 Terminated job 543367.0 from status 0 duration 31
08/01/14 09:08:55 Starting job 544385.0 from
08/01/14 09:09:43 Terminated job 544385.0 from status 0 duration 48

This messages are generated by parsing_starterlog.awk which parses log/StarterLog file
Each line that says Terminated job 543367.0 from status 0 duration
indicates that the Startd actually started a starter and the starter also launched a child process which actually ran the user job.
So, the title of this ticket "even if startd fails to start/run a matched job." is not accurate..

  • Status changed from New to Resolved
  • % Done changed from 70 to 100

Parag was wondering if the current code handles the case of multicore jobs
and the shows it does so.
slotlogs="`ls -1 ${main_starter_log} ${main_starter_log}.slot* 2>/dev/null`"

So, we will close this ticket.
In conclusion, we made sure that the current code ( and its children scripts) handle
error reporting properly.
