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.
