Hi [~andrew.wang], please see attached screenshot which illustrates exactly what I am trying
to do.
You will see on the right hand side that the property description is not available with the
current values being duplicates of the <property><name>.
This is due to the code currently not parsing out the values for the property descriptions.
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java#L2661-L2692

I wanted to see if I could @override Configurtion#loadResource(Properties properties, Resource
wrapper, boolean quiet) but I can't.

> Over on the [common-dev|http://www.mail-archive.com/common-dev%40hadoop.apache.org/msg16099.html]
ML I explained a use case which requires me to obtain the value of the Configuration <description>
tags.
> [~cnauroth] advised me to raise the issue to Jira for discussion.
> I am happy to provide a patch so that the <description> values are parsed out of
the various XML files and stored, and also that the Configuration class is augmented to provide
accessors to accommodate the use case.
> I wanted to find out what people think about this one and whether I should check out
Hadoop source and submit a patch. If you guys could provide some advice it would be appreciated.
