[HTCondor-users] starting htcondor interactive jobs?

[Aki Ketolainen <akik@xxxxxxxxxxx>]

Hi,

I have setup a small htcondor v8.4.7 system on CentOS 6.8.
At this time it's just two machines with one having COLLECTOR, MASTER, 
NEGOTIATOR and SCHEDD
and the other with MASTER and STARTD.

A vanilla batch job goes thru quickly but I'm having some problems with 
interactive jobs.

Question 1) A "condor_submit -interactive" job is started ok but the 
time delay that it takes
to open a shell from the STARTD host varies from a few seconds up to 20 
seconds.
There are no error messages output in the shell:

$ condor_submit -interactive
Submitting job(s).
1 job(s) submitted to cluster 45.
Waiting for job to start...
Welcome to server-a.example.com!
You will be logged out after 7200 seconds of inactivity.

When the interactive job is trying to start i can see this in SchedLog:

==> SchedLog <==

How could I debug this further, why it randomly takes a long time to 
open an interactive job?

Question 2) Is there a way to start a X11 application directly through a 
"condor_submit -interactive" command?
This would be very useful in our use case. For example "condor_submit 
-interactive editor"

Best regards,

Aki
