-----------------------------------

[~aw] I wonder if you are still seeing the issue with the current code base?

> web interfaces are not logged until after opening

>                 Key: HADOOP-9522
>                 URL: https://issues.apache.org/jira/browse/HADOOP-9522
>             Project: Hadoop Common
>          Issue Type: Improvement
>    Affects Versions: 2.0.4-alpha
>            Reporter: Allen Wittenauer
>
> If one mis-configures certain interfaces (in my case 
> yarn.resourcemanager.webapp.address), neither Hadoop nor jetty throws any 
> errors that the interface doesn't exist. Worse yet, the system appears to be 
> hung. It would be better if we logged what hostname:port we were attempting 
> to open before we opened it.
