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.

Important: Only certain properties in bdd.conf in the $BDD_HOME/BDD_manager/conf directory can be updated. Modifying others can prevent your BDD cluster deployment from starting properly. For more information, see Configuration properties that can be modified.

The bdd-admin script with the refresh-config command runs on the entire BDD cluster. You cannot specify a particular component or host for it to run on.

After you run the script with refresh-config, you must restart the BDD cluster for the changes to take effect.

To refresh the BDD cluster configuration:

On the Admin Server, open bdd.conf in the $BDD_HOME/BDD_manager/conf directory, in any text editor and make the desired changes.
Be sure to save the file before closing.
Run the following from the command line:
```
./bdd-admin.sh refresh-config <configuration_file>
```
Where <configuration_file> is the relative path to the edited version of bdd.conf.
Activate the new configuration by running the following from the command line:
```
./bdd-admin.sh restart --all
```

Example

The following commands copy bdd.conf from the Admin Server to all other nodes, then restart the cluster:

./bdd-admin.sh refresh-config ../bdd.conf
./bdd-admin.sh restart --all
