Subject [jira] Commented: (HADOOP-6408) Add a /conf servlet to dump running configuration
Date Thu, 03 Dec 2009 11:32:20 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12785276#action_12785276

Steve Loughran commented on HADOOP-6408:
----------------------------------------

-you don't need to generate an HTML version if you include a URL to a locally served XSL file,
IE and FF will use the style sheet. 
-Alternatively, consider some XHTML

Or don't bother, just have something that is easy to attach to bug reports. 

One worry: security. Does anyone put passwords in their configurations? If so, this would
expose it. Accordingly, it may be useful to make this a feature which can be disabled.

> HADOOP-6184 added a command line flag to dump the running configuration. It would be
great for cluster troubleshooting to provide access to this as a servlet, preferably in both
JSON and XML formats. But really, any format would be better than nothing. This should/could
go into all of the daemons.
