This is due to sentences such as

  "If set, and the file can't be read, the job enters the state
   DRMAA_PS_FAILED. The attribute name is drmaa_input_path."

in DRMAA spec.

Possibly with the Condor implementation a "drmaa_transfer_files" setting
"ioe" is in effect by default. This would imply these files are located
at the submit machine. At least this would be an explaination how Condor
can detect at submit time these pathes are invalid.

In case of Grid Engine "DRMAA_PS_FAILED" is returned as the defectiveness
of these pathes at the execution machine can't be determined before the
try to start the job.
