> Currently, FSNamesystem writes audit logs to a logger; that makes it easy=
 to get audit logs in some log file. But it makes it kinda tricky to store =
audit logs in any other way (let's say a database), because it would requir=
e the code to implement a log appender (and thus know what logging system i=
s actually being used underneath the fa=C3=A7ade), and parse the textual lo=
g message generated by FSNamesystem.
> I'm attaching a patch that introduces a cleaner interface for this use ca=
se.
