[HA] Starting standby node in HA

[Fernando O.]

Hi All,
    I'm trying to setup a HA cluster, I started (and formatted) one
namenode, resourcemanager and zkfc.

Now I'm not sure how to startup the sencond (standby) namenode, I ssh to
the box and executed
sbin/hadoop-daemon.sh start namenode

but it tries to start the "primary" namenode and not the one I'm in

is that a config problem? should I use a different command?
