> The configuration setting {{dfs.datanode.dns.interface}} lets the DataNode 
> select its hostname by doing a reverse lookup of IP addresses on the specific 
> network interface. This does not work {{when /etc/hosts}} is used to setup 
> alternate hostnames, since {{DNS#reverseDns}} only queries the DNS servers.
