Todd Lipcon updated HADOOP-6408:
--------------------------------
Attachment: hadoop-6408.txt
New patch to address findbugs and javac warnings:
- Added a serialVersionUID to ConfServlet (apparently Servlets are
serializable)
- Added some more synchronized blocks in Configuration - was missing some
synchronization while iterating over properties, etc, which was exposed as a
side effect of adding some code.
The other findbugs warning was about the catch (Exception) in writeXml, which
already existed. I'd be happy to explicitly catch the thrown XML-related
exceptions and rethrow as an IOException, but I didn't write that patch and
didn't want to change it if it were purposefully a RuntimeException. Thoughts?

> 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.
