[jira] Created: (HADOOP-3715) Change all references of dfs to hdfs in configs

Change all references of dfs to hdfs in configs
-----------------------------------------------

                 Key: HADOOP-3715
                 URL: https://issues.apache.org/jira/browse/HADOOP-3715
             Project: Hadoop Core
          Issue Type: Bug
          Components: dfs
    Affects Versions: 0.19.0

After code restructuring dfs has been changed to hdfs, but I see config variables with dfs.<something> eg dfs.http.address. Should we change everything to hdfs?

[jira] Commented: (HADOOP-3715) Change all references of dfs to hdfs in configs

Posted by "Doug Cutting (JIRA)" <ji...@apache.org>.

Doug Cutting commented on HADOOP-3715:
--------------------------------------

If we do this, it must be back-compatible.  In the first release after the change it should still accept the old names but print warnings.  The suggested way to do this is to add static accessor methods for each such parameter and replace all accesses to the parameters with calls to the accessor methods.  Then back-compatibility can be handled centrally in the accessor methods.  Perhaps all of the accessor methods can even share a back-compatiblity mechanism.
