Subject [jira] Commented: (HADOOP-6317) Serialize the 'final'ness of Configuration keys
Date Mon, 19 Oct 2009 18:07:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6317?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12767428#action_12767428

Aaron Kimball commented on HADOOP-6317:

The "new" findbugs warning refers to the {{try .. catch (Exception)}} block in {{writeXml()}}.
This shouldn't be new; the lines I added to the method shouldn't affect the utility of this
try block. Nevertheless, findbugs seems to be picking this up for the first time now.

I can either remove the try..catch block from the method, or we can up the acceptable findbugs
warning count. Someone else want to weigh in?

> Currently Configuration.writeXml doesn't serialize the 'final' attribute. There are some
scenarios where it is useful:
> # TaskTracker should mark the tasks' 'localized' parameters as 'final' 
> # GUI tools
