Re: [Condor-users] configure condor with environment vaiables

You should check your environment and make sure the escaping was correct.

$ export _CONDOR_START=Owner=="xxx"||Owner=="yyy"
06:33:38am> eeyore:~/Documents/CondorInstallation $ echo $_CONDOR_START 
Owner==xxx
$ export _CONDOR_START='((Owner == "xxx") || (Owner == "yyy"))' 
$ echo $_CONDOR_START
((Owner == "xxx") || (Owner == "yyy"))

export with the ''s works for me in my shell.
You should also figure out why the environment was used to configure condor and evaluate if it is still necessary.

Hi Matt,

Thanks for the explanation. However,
export _condor_START=((Owner=="xxx")||(Owner=="yyy")) did Not work, still have the error of "required attribute START is not defined".
I also tested export _condor_START=Owner=="xxx"||Owner=="yyy" (note with brackets removed), it could start the daemon, but it did not accept any jobs either from xxx or yyy.

The only two worked fine until now are:
export _condor_START=true
export _condor_START_owner="xxx"

Any idea? Thanks.

Hao

Hi,

My predecessor configured condor by using environment variables, such as
export _condor_START_owner=${USER}.
I understand this is to config START expression with owner attribute.
But how does this work?

This is only ref I found: "Some Condor tools utilize environment
variables to set their configuration. These tools search for
specifically-named environment variables. The variables are prefixed by
the string_CONDOR_or _condor_. The tools strip off the prefix, and
utilize what remains as configuration."

Following the format I made some change, but some worked some did not work:

export _condor_START=true (work, allow any one to run jobs)
export _condor_START=((Owner="xxx")||(Owner="yyy")) - doesn't work,
error "Required attribute "START" is not defined"
export _condor_START_owner="xxx"||"yyy" - "Required attribute "START" is
not defined"

so how to configure condor by environment variables, this prefix suffix way?

Thanks,
Hao


Wow, that's a gem. START_owner is a param just as START is. START_owner should probably fade into history, if it hasn't already.

'START_owner = ""xyz""' will generate 'START = Owner == "xyz"', or in your case 'START = Owner == ""xxx"|"yyy""', which has no hope of working. I recommend purging START_owner from your memory.

That illustrated the problem though,

export _condor_START=((Owner=="xxx")||(Owner=="yyy"))

should work. Given the appropriate shell escaping. Note == vs =.

You are correct in thinking "_condor_" is the prefix Condor will use to pick up configuration from the environment.

Best,
