Description

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.
