Philip Zeyliger commented on HADOOP-5687:
-----------------------------------------
bq. By generating the description in the name-node you can only add that this
is coming from the NameNode. But that will be seen in the stack trace one way
or another.
This is the only place where I can reference the config property that this
magically came out of.
I've added the check for NetUtils. Uploading the latest patch.
