> Currently in HA setup (with logical URI), the DFSAdmin#refreshNodes command is sent to
the NameNode first specified in the configuration by default. Users can use "-fs" option to
specify which NN to connect to, but in this case, they usually need to send two separate commands.
We should let refreshNodes be sent to both NameNodes by default.
