Re: [HTCondor-users] Dynamically changing HTCondor configuration when using python binding

[Brian Lin <blin@xxxxxxxxxxx>]

Hey Marco,

For 1), you can change the interpreter's environment so htcondor.reload_config() will respect that. For example, on a test CE:

# python -c 'import htcondor; import os; print htcondor.param["COLLECTOR_HOST"]; os.environ["CONDOR_CONFIG"] = "/etc/condor-ce/condor_config"; htcondor.reload_config(); print htcondor.param["COLLECTOR_HOST"]'
