Jim Plush commented on HDFS-1321:
---------------------------------

thanks for the info Aaron, those are all definitely reasonable requirements and 
I should have caught those on the first round. Let me know if this patch takes 
care of those issues. 


> If service port and main port are the same, there is no clear log message 
> explaining the issue.

> With the introduction of a service port to the namenode, there is now a 
> chance for user error to set the two port equal.  This will cause the 
> namenode to fail to start up.  It would be nice if there was a log message 
> explaining the port clash.  Or just treat things as if the service port was 
> not specified.
