> We need to access HDFS on an AWS installation from outside the AWS firewall.  The technique
is described here:
> 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.
