> We need to access HDFS on an AWS installation from outside the AWS firewall.  
> The technique is described here:  
> http://rainerpeter.wordpress.com/2014/02/12/connect-to-hdfs-running-in-ec2-using-public-ip-addresses/
> In order to do this we need to set the 
> "dfs.client.use.datanode.hostname=true" in an alternate configuration file 
> set after the default configuration is loaded.
> I propose to add a property "configName" to HdfsFileSystemConfigBuilder, and 
> then code in HdfsFileSystem to get the value of the property and set it in 
> the Configuration.
