I think that there might be an inconsistency in getHostname. 
The comments(If the hostname cannot be resolved, then a string version of the IP address is returned) are not compliant with the behavior of the method.

I think that there might be an inconsistency in getHostname. 
If the hostname cannot be resolved, then a string version of the IP address should be returned.
Instead, if  getnameinfo fails, an error string corresponding to the error code is returned by gai_strerror.

> https://issues.apache.org/jira/browse/MESOS-672 was committed in 0.18.0 which fixed redirection of WebUI. Included in this fix is https://reviews.apache.org/r/17573/ which changed how the SlaveInfo.hostname is calculated when "--hostname" is not provided. Specifically, slave now deduces the hostname from "--ip" flag when "--hostname" is not provided.
> We should update the slave/master flags and documentation (http://mesos.apache.org/documentation/latest/configuration/) reflecting this change.
