[HTCondor-users] $(FULL_HOSTNAME)

Hi HTCondor team,

How does HTCondor determine $(FULL_HOSTNAME)? Is there a difference in how it is determined between EL6 and EL7? I ran into a problem with a simple, out-of-the-box personal condor pool install not working on EL6 [1] [2], but it is working with no problem on EL7 [3] [4]. 

I know the problem has something to do with how the local system is configured. The problem occurs on a CentOS 6 image booted up on a local OpenStack cluster. However, the error is not observed when I perform the same install on a CentOS 6 image on AWS. 

This is not an urgent matter. But when you get the chance, perhaps you can provide a possible explanation. I'd like to understand better what maybe causing the difference in behavior.
