Job exit after 5-10 seconds after start.

Issue #67 resolved
IT Expert created an issue

Hi. After switching to develop branch jobs just exit after 5-10 seconds after start. Nothing wrong in logs. Looked at scheduler logs, mesos slave logs - no any errors.

2018-02-23 11:52:25,840 DEBUG [godocker-scheduler][Thread-1] Task placed on host host1
2018-02-23 11:52:25,840 DEBUG [godocker-scheduler][Thread-1] Mesos:Task:Running:84

2018-02-23 11:52:29,844 DEBUG [godocker-scheduler][Thread-1] Task 84-0 is in state TASK_FINISHED

Tried to stop god-watcher, but no luck. Tried on 2 different test env. with the same result.

Could you advise, how to debug this situation, or could you try to start job with "sleep 600" or some long time job for test ?

    we see in logs that Mesos sent the TASK_RUNNING and TASK_FINISHED almost immediatly. The ~5s delay is the time for watcher to detect the information and do the termination/cleanup. Script executed as expected and ended immediatly (at least this is what mesos says...). Task finished , for mesos, means script was executed and ended with exit code 0.

    What do you mean by " start job with sleep 600" ?

    in the godocker cmd script, you execute a shell script with whatever you want, so it can be a sleep if you want.

    I mean if I'll run job like this:

    echo "Hello GoDocker", it will finish ok.

    But if i'll run longer task, for example:

    echo "Hello GoDocker"
sleep 500
echo "After 500 seconds"

    it will finish after 5 secs, and log will have only "Hello GoDocker" without any error.

    for example, real test job, that was worked fine on master branch, now it just exit after 6 secs.

    Exit code   0

    I made a local test with "longer" job, and it worked fine.

    nothing in err file?

    Mesos says job ended correctly, so if job ends, should have information. Did you enable some quotas?

  5. Olivier Sallou repo owner

    did you also checked system logs on mesos slave where task was executed ? (some docker errors... appear in system logs)

  8. IT Expert reporter

    nothing in err file? empty Did you enable some quotas? no. all by default. no overquota messages.

    checked system logs

    Are you using docker containerizer or unified containerizer ? (mesos/unified in go-d.ini)

    Are you using docker containerizer or unified containerizer ? (mesos/unified in go-d.ini)

    unified conteinerizer, mesos executor, because of GPU.

OK

    I made a local test with unified containerizer (not my default), but still work. But something happens within mesos container/your script.

    I0223 13:52:26.118549 25209 executor.cpp:477] Running '/usr/libexec/mesos/mesos-containerizer launch <POSSIBLY-SENSITIVE-DATA>'

    your script exits with exit code 0 immediately.

    As some logs of the godocker script appears, it means that job is executed (else would stop at init and god.log and god.err would be empty). But why does the script stops "in the second" ??? Once script is started on mesos, godocker is "out" of the process, godocker just waits for a message from mesos about completion(ok or ko).

    And if something goes wrong in the script, it should fail with an exit code > 0.....

    Do you see the god_sys.err file in godocker job dir (next to god.log and god.err) ?

  13. IT Expert reporter

    wrapper.sh was changed:

    /mnt/go-docker/godocker.sh -> /mnt/go-docker/godocker.sh &> /mnt/go-docker/god_sys.err

    may be when godocker.sh starts in background container exits ?

    is it could be a problem there ?

  14. Olivier Sallou repo owner

    it creates a new log file to catch startup errors in god_sys.err file. I use it and have no issues with it. You should see this file in your job dir next to god.log and god.err.

  15. IT Expert reporter

    YES!!!! that it!!! Just remove it in scheduler. Now it works.

    & -> fork process in background may be you forgot "2" 2> ?

  16. Olivier Sallou repo owner

    godocker.sh does not start in background. It is executed and forwards both stdout and stderr to god_sys.err

  18. Olivier Sallou repo owner

    in fact seems to depend on executed shell..... in ubuntu debian

    #!/bin/sh
echo "hello" &> titi

    forks and do not redirect

    on centos, stdout/stderr is redirected. I made my tests on centos..... So I need to find a fix that works on both..... I gonna remove it in the meanwhile

  19. Olivier Sallou repo owner

    I have removed the god_sys log redirection in dev and pushed commit , new container is building. Will try to find a way to get the expected redirection on all OS...

  20. Olivier Sallou repo owner

    the following seems to do the job on both deb/centos OS.

    >> /mnt/go-docker/god_sys.err 2>&1

    will update code soon, in the meanwhile, redirection has been removed.
