Re: [HTCondor-users] Upgrading from 7.5.5

[Tim Theisen <tim@xxxxxxxxxxx>]

Hi Szabolc,

I have answers to your questions.

Yes, you can configure the permissions of the directories that are created (provided you have at least version 8.1.3 or version 8.0.7 (to be released)). There is a new setting JOB_EXECDIR_PERMISSIONS that controls those permissions. Take a look at the entry for it in the manual.

http://research.cs.wisc.edu/htcondor/manual/v8.1/3_3Configuration.html#SECTION004313000000000000000

There is a new command called condor_tail that can be used to watch the stdout/stderr for a job.

Hi Brian,

First of all, thanks for the assistance!

Wow, that's an old version!

Yeah, if it ain't broke, don't fix it... ;) The only problem is that when you find that it is actually broken, you might be off with years of releases...

Here's what I would do:
1) Upgrade a single worker node and only allow it to accept jobs from a test user.  See if this works.

I did what you suggested and the first step seems to be working nicely, with one minor exception:
7.5.5 used to create the startd worker directories in /tmp with permissions 755 while 8.1.4 creates them with 700.
I know that these are not "public" directories but we have some jobs that run for a long time and we let the users look into the work-in-progress stdout/stderr logs by using a GUI. Can we somehow configure what permission these directories created with? (BTW the file in there are still 755, so its just the directory that blocks other users.) Or is there an "official" solution for getting these logs like the fetching tools for system and user logs?

Cheers,
Szabolcs
