Robert Joseph Evans commented on HADOOP-8525:
---------------------------------------------

Yes that would make since to update the Writable methods.  I remember looking and they are
not really used, but they are still there.

> Configuration provides basic traceability to see where a config setting came from, but
once the configuration is written out that information is written to a comment in the XML
and then lost the next time the configuration is read back in.  It would really be great to
be able to store a complete history of where the config came from in the XML, so that it can
then be retrieved later for debugging.
