First of all, is there any particular reason you don't want to have the 
two log files?

There are two ways you can avoid having duplicate user logs for your jobs:

1) Don't specify log files in your submit files.
2) Set DAGMAN_ALWAYS_USE_NODE_LOG to false in a per-DAG configuration
   file (or some other configuration setting).

There are issues with both of these alternatives -- if you do #1, you 
won't get log files if you ever run your jobs outside of a DAG.  If you do 
#2, you'll potentially increase DAGMan's file descriptor usage, and 
decrease performance a bit.  (Also, the #2 option may go away in the 
future.)

In general, unless you have some reason that the duplicate logs are really 
a problem, we recommend leaving things the way they are.
