Re: [HTCondor-users] HTCondor matchmaker and permissions problem.

You should _not_ make your executable world writable. Someone else on the system could potentially change the script to do something nasty, and then you would execute it. You can use 'chmod 755' instead.
FWIW, a safe, self-documenting way to do this without inadvertently adding global write (or read!) permissions to a file is to 'chmod +x' it.

As per the permission issue, you have to make sure the script in the condor executable is indeed executable. You can do this by changing file permissions with chmod 777 (filename).

Hi all,

I am working on a Policy for HTCondor setup for a cluster at ICTS [1].
I have installed and configured condor on my laptop for now and I am
facing two issues.

1. CONDOR MATCHMAKER:

When I submit a job, it sits idle for a long time (around 20 mins). On
doing _condor_q - analyze _the result says:

 " 005.000:  Request has not yet been considered by the matchmaker"

Now I want to know how to increase the rate at which the _matchmaker
_looks for the jobs in the queue.


In your condor_config, you can set NEGOTIATOR_INTERVAL to something like 15 seconds and jobs will be considered more often.

You can also run the command "condor_reschedule" to hint to the matchmaker to try again.



2. PERMISSION ISSUE:

Eventually after 20 minutes or so when the job starts, it goes into
the HOLD state, with the following error in the logs

012 (005.000.000) 12/10 15:55:33 Job was held.
 Error from slot2@sameem-Ideapad: Failed to open
'/home/sameem/Desktop/condor/testjob/outputfile' as standard output:
Permission denied (errno 13)
 Code 7 Subcode 13


This isn't related to the executable file, but rather HTCondor is trying to open that file to store your stdout for the job.  Presumably you specified this by setting "output" in your job submit file.  Does that path exist, and is writable by you?  Outside of HTCondor, try:
 touch /home/sameem/Desktop/condor/testjob/outputfile

and if that doesn't work try to figure out why.  Maybe the ownership or permissions are incorrect on the parent directories.  It might also depend on what user you are running HTCondor as (root?  condor?  yourself?)


Cheers,
-zach
