> {{NameNodeRpcServer}}, {{FSNameSystem}} and {{FSDirectory}} implement the namespace of
the NN. In the current implementation the boundary of these classes are not fully clear.
> This jira tracks the efforts of clarifying the boundaries between these three classes
so that they can be more easily maintained in the long term.
