The most common reason that I have seen is that Condor has been configured 
to have a different FILESYSTEM_DOMAIN on each machine--it's set to be the 
full hostname. If you don't tell Condor to transfer files, it assumes that 
there isn't a shared filesystem between computers (like NFS) if the 
FILESYSTEM_DOMAINs on two machines are different.

So: if you have a shared filesystem, FILESYSTEM_DOMAIN should be the same. 
If you don't have a shared filesystem, you need to tell Condor to transfer 
files.

See Sections 2.5.3 and 2.5.4 of the Condor 6.5 manual for more information.

There are some other common reasons for this problem. See this question in 
the  FAQ from the manual.
