Affects Version/s: None
Fix Version/s: 0.21.0
Keys in configuration files should be standardized so that key names reflect the components they are used in.
dfs.backup.address should be renamed to dfs.namenode.backup.address
dfs.data.dir should be renamed to dfs.datanode.data.dir
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.
