Administering Big Data Discovery with the bdd-admin Script

This section describes the bdd-admin script and how you can use it to perform different administrative operations for the Dgraph, the Dgraph HDFS Agent, Studio, and the Dgraph Gateway.

About the bdd-admin script
You can use the bdd-admin script to perform a number of administrative tasks for the BDD cluster from the command line.
Refreshing cluster configuration
You update the configuration for the entire Big Data Discovery cluster by making the desired changes to the bdd.conf file on the Admin Server, then running the bdd-admin script with the refresh-config command. This command uses the SCP protocol to copy bdd.conf from the Admin Server to all other nodes in the cluster.
