> Currently FSDirectory implements a barrier in {{waitForReady()}} / {{setReady()}} so
that it only serve requests once the FSImage is fully loaded.
> As a part of the effort to evolve {{FSDirectory}} to a class which focuses on implementing
the data structure of the namespace, this jira proposes to move the barrier one level higher
to {{FSNamesystem}}.
