[jira] [Created] (HADOOP-9522) web interfaces are not logged until after opening

Allen Wittenauer created HADOOP-9522:
----------------------------------------

             Summary: 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.
