+ This script is used to configure cluster parameters on this
+ controller. The user should restart controller to apply changes.
+
+ Usage: $0 <seed_nodes_list>
+ - seed_nodes_list: List of seed nodes, separated by comma or space.
+
+ The script checks that one (any) of the the controller's active IP
+ addresses is present in the seed_nodes_list. When running this script
+ on multiple seed nodes, keep the seed_node_list same on all nodes.
+
+ Optionally, shards can be configured in a more granular way by
+ modifying the file "custom_shard_configs.txt" in the same folder
+ as this tool. Please see that file for more details.
+
+This script is currently limited to IPv4 addresses. If you have
+problems running this script, please use 'configure_cluster.sh'.
