[jira] Commented: (HADOOP-4365) Configuration.getProps() should be made protected for ease of overriding

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-4365?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12637567#action_12637567 ] 

Doug Cutting commented on HADOOP-4365:
--------------------------------------

JobConf will soon go away, with HADOOP-1230.

That said, letting folks override getProps() sounds fine.  This revives the spirit of HADOOP-24.

> HADOOP-4293 does make Configuration cleaner and easier to work with, but it does contain assumptions about how configurations are represented (in a private Properties instance) that subclasses may wish to diverge from.
> By making getProps() protected, people who subclass JobConf or Configuration can do their own binding from configuration data to Properties.
