Description

While navigating from web page (eg: /cluster/app/<app-id> ) to HS, browser displays IP address rather than hostname.

JobHistoryUtils.java

    if (address.getAddress().isAnyLocalAddress() || 
        address.getAddress().isLoopbackAddress()) {
      sb.append(InetAddress.getLocalHost().getHostAddress());
    }	
}

I think it is better to use hostname rather than IP address.
