-------------------------------------------
Summary: Provide Improved Traceability for Configuration
Key: HADOOP-8525
URL: https://issues.apache.org/jira/browse/HADOOP-8525
Project: Hadoop Common
Issue Type: Improvement
Reporter: Robert Joseph Evans
Priority: Trivial
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.
