Subject [jira] Created: (HDFS-531) Renaming of configuration keys
Date Thu, 06 Aug 2009 18:02:14 GMT
Renaming of configuration keys
------------------------------

                 Key: HDFS-531
                 URL: https://issues.apache.org/jira/browse/HDFS-531
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Jitendra Nath Pandey
            Assignee: Jitendra Nath Pandey
             Fix For: 0.21.0


Keys in configuration files should be standardized so that key names reflect the components
they are used in.
For example:
   dfs.backup.address should be renamed to dfs.namenode.backup.address 
   dfs.data.dir   should be renamed to dfs.datanode.backup.address

This change will impact both hdfs and common sources.
Following convention is proposed:
1. Any key related hdfs should begin with 'dfs'.
2. Any key related to namenode, datanode or client should begin with dfs.namenode, dfs.datanode
or dfs.client respectively.
