Subject [jira] Commented: (HADOOP-6408) Add a /conf servlet to dump running configuration
Date Wed, 30 Dec 2009 20:56:29 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795443#action_12795443
] 

Tom White commented on HADOOP-6408:
-----------------------------------

* The catch block in writeXml() can actually be removed without changing behaviour, since
the method already declares that it throws IOException, and any RuntimeException is re-thrown.
This would remove the FindBugs warning.
* The javadoc on the writeXml(Writer) method is incorrect since it refers to OutputStream.

> 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.
