>
> 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.
