> With the current Chukwa log4j implementation, if you define a static log4j configuration
the appender is initialized at creation time.
> This may cause some problems for example with Hadoop Audit log or Metrics context, if
the log4j properties are statically defined then a userX running an hadoop command will trigger
a permission denied exception since the appender will try to initialize itself and therefore
try to create a file under userX ownership for each appender even if not data is going to
be written to it.
> The goal is to delay this initialization until the first message is actually written
to that log so this kind of issue could easily be avoided.
