Description

From OSS Mesos Slack:
I recently tried upgrading one of our Mesos clusters from 1.1.0 to 1.2.0. After doing this, it looks like the zk field on the /master/flags endpoint is no longer present.

This looks related to the recent Flags refactoring that was done which resulted in some flags no longer being populated since they were not part of master::Flags in src/master/flags.hpp.
