Subject [jira] [Commented] (HADOOP-8525) Provide Improved Traceability for Configuration
Date Thu, 21 Jun 2012 20:47:42 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13398837#comment-13398837
] 

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

I think the only big change here is a small addition to the XML format, so that we can add
in a list of previous files it was read from and remove the comment that more or less gives
the same information.  Internally the Map storing this into will have to now point to a list
instead of a single value.  It looks fairly straight forward.

> 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.
