Haohui Mai commented on HDFS-7416:
----------------------------------
Ideally audit log should be as close as the user-facing interface as possible.
The current implementation, however, captures additional information in the
audit log (e.g., the audit log of mkdirs() / create() also has file stat
information). I think it is okay to leave it in {{FSNameSystem}}.

> {{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.
