This command uses the SCP protocol to copy bdd.conf from the Admin Server to all other nodes in the cluster.

For example, changing the value of ADMIN_SERVER would prevent Big Data Discovery from starting.

Services that have autostart enabled start automatically after their host machines are rebooted.
