Description

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.
