Subject [jira] [Resolved] (HADOOP-2644) Remove the warning for attempting to override a final parameter
Date Wed, 28 Dec 2011 23:25:33 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-2644?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Harsh J resolved HADOOP-2644.
-----------------------------

    Resolution: Won't Fix

I disagree that we should remove this. It may be noise to a developer, but its good information
for those who need to maintain and support them. Its a great indicator sometimes that the
client configs are tweaked or are out of sync. There are a lot of other benefits I've seen
as a result of this in the field.

However, we (very recently) did stop logging that if the overriding value is the same.
