> 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}}.
