Debugging worker logs live at UChicago

[alexander-held]

On coffea.af.uchicago.edu, which scales to HTCondor, one debugging method that can be quite helpful is reading along with worker logs live: use a single (or multiple) workers, look up their ID in the info tab, then connect to the worker with e.g. condor_ssh_to_job 3652712.0, read along with tail -f _condor_stderr.
