      Description

      dfsadmin currently fails over like other clients, so if we you want to put a particular NN in safemode you need to use the "fs" option and specify a host:ipcport target. Like HDFS-2808 it would be useful to be able to specify a logical namenode ID instead of an RPC addr. Since fs is part of generic options this could potentially apply to all tools, however most tools want to refer to the default logical namenode URI and failover like other clients.
