> 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.
