> HDFS-1623, and potentially other HDFS features will use the nameservice abstraction,
even if federation is not enabled (eg you need to configure {{dfs.federation.nameservices}}
in HA even if you're not using federation just to declare your nameservice). This is confusing
to users. We should consider deprecating and removing "federation" from the {{dfs.federation.nameservices}}
and {{dfs.federation.nameservice.id}} config options, as {{dfs.nameservices}} and {{dfs.nameservice.id}}
are more intuitive.
