Subject [jira] [Commented] (HADOOP-12021) Augmenting Configuration to accomodate <description>
Date Tue, 26 May 2015 20:01:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12021?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14559745#comment-14559745
] 

Andrew Wang commented on HADOOP-12021:
--------------------------------------

Lewis, could you give a little more detail of your Nutch usecase?

It's also worth noting that while we provide the description in core-default.xml / hdfs-default.xml
/ etc for documentation, but probably not in user-provided config files. The -default.xml
files are already included in our JARs, so it shouldn't increase dependency size. Loading
them in will, however, increase in-memory size, which is probably a concern for some user
app.

> 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.
