Subject [jira] Commented: (HADOOP-4631) Split the default configurations into 3 parts
Date Fri, 05 Dec 2008 17:52:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4631?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12653874#action_12653874
] 

Doug Cutting commented on HADOOP-4631:
--------------------------------------

Back-compatibility is a concern.  I think we should still always look for and load hadoop-site.xml
but not hadoop-default.xml.  When we find and load hadoop-site.xml we should emit a warning.

> We need to split hadoop-default.xml into core-default.xml, hdfs-default.xml and mapreduce-default.xml.
That will enable us to split the project into 3 parts that have the defaults distributed with
each component.
