[HTCondor-users] Condor usage by users

[Wadud Miah <W.Miah@xxxxxxxxxxx>]

Hi,

I installed Condor using RPMs as described below as the root user:

# wget https://research.cs.wisc.edu/htcondor/yum/RPM-GPG-KEY-HTCondor

# rpm --import RPM-GPG-KEY-HTCondor

# cd /etc/yum.repos.d

# wget https://research.cs.wisc.edu/htcondor/yum/repo.d/htcondor-stable-rhel7.repo

# yum install condor condor-externals

# echo "DAEMON_LIST = MASTER, SCHEDD" >>/etc/condor/config.d/50-main.config

# systemctl start condor

# systemctl enable condor

The server is listening to port 9618:

# netstat -tulpen | grep 9618

tcp        0      0 0.0.0.0:9618            0.0.0.0:*               LISTEN      446        3812746    2127692/condor_shar

tcp6       0      0 :::9618                 :::*                    LISTEN      446        3812747    2127692/condor_shar

When I type condor_q as the root user, it shows an empty queue:

# condor_q

-- Schedd: cyan54 : <152.78.188.182:16413> @ 11/28/23 13:25:40

OWNER BATCH_NAME      SUBMITTED   DONE   RUN    IDLE   HOLD  TOTAL JOB_IDS

Total for query: 0 jobs; 0 completed, 0 removed, 0 idle, 0 running, 0 held, 0 suspended

Total for all users: 0 jobs; 0 completed, 0 removed, 0 idle, 0 running, 0 held, 0 suspended

However, when I type condor_q as a user, I get an error:

$ condor_q

Error:

Extra Info: You probably saw this error because the condor_schedd is not

running on the machine you are trying to query. If the condor_schedd is not

running, the Condor system will not be able to find an address and port to

connect to and satisfy this request. Please make sure the Condor daemons are

running and try again.

 

Extra Info: If the condor_schedd is running on the machine you are trying to

query and you still see the error, the most likely cause is that you have

setup a personal Condor, you have not defined SCHEDD_NAME in your

condor_config file, and something is wrong with your SCHEDD_ADDRESS_FILE

setting. You must define either or both of those settings in your config

file, or you must use the -name option to condor_q. Please see the Condor

manual for details on SCHEDD_NAME and SCHEDD_ADDRESS_FILE.

I am new to Condor (have installed it because Pegasus requires it), so any help will be greatly appreciated. I've looked at the documentation here (https://htcondor.readthedocs.io/en/latest/admin-manual/configuration-macros.html#SUBSYSTEM), but I can't make any sense of it.

Regards,
