             Summary: Webui does not show frameworks/executor when hostname is unreachable
                 Key: MESOS-8523
                 URL: https://issues.apache.org/jira/browse/MESOS-8523
             Project: Mesos
          Issue Type: Bug
          Components: webui
    Affects Versions: 1.4.1, 1.3.1, 1.5.2
         Environment: Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.43-2 (2017-04-30) x86_64 GNU/Linux
            Reporter: longfei

Here is my case: I have a  machine with an IP 10.115.13.142, whose hostname is n115-013-142.byted.org. However, it is a cloud machine in a foreign region. And I can only visit it with IP, but not hostname.

As a result,  I can't see any frameworks/executors from the Webui since the /state and /monitor/statistics APIs are all called with {color:#333333}hostnames{color}.

I {color:#FF0000}replaced hostnames with IPs{color} and it worked fine.

So I'm wondering what's the advantage of using hostnames over IPs.
