Chuan Liu updated HDFS-4320:
----------------------------

    Attachment: HDFS-4320-trunk.3.patch

Attaching a new patch; the fix is the same as previous one only using the 
existing key "dfs.namenode.rpc-address". I believe this is correct behavior 
because the error message suggests the address should be 
"dfs.namenode.rpc-address"  in {{validateConfigurationSettings(final 
Configuration conf)}} method.
                
> Add a separate configuration for namenode rpc address instead of only using 
> fs.default.name

> When NameNode starts up, it tries to find out its address by looking at the 
> fs.default.name configuration key instead of using its own keys. This breaks 
> scenarios where we try to configure a Hadoop cluster that uses a different 
> default file system than DFS, but still try to prop up namenode and datanode 
> services as a secondary file system.
