By default, an ApsaraDB for HBase cluster blocks all external clients. To allow your applications to connect, configure an IP address whitelist or add Elastic Compute Service (ECS) security groups as whitelists for the cluster.
Choose a method
| Method | Best for |
|---|---|
| IP address whitelist | Allowing access from specific IP addresses or CIDR blocks |
| ECS security groups | Allowing access from multiple ECS instances without managing individual IP addresses |
Prerequisites
Before you begin, ensure that you have:
An ApsaraDB for HBase Standard Edition cluster
Configure the whitelist
The whitelist configuration steps for ApsaraDB for HBase Standard Edition are the same as those for ApsaraDB for HBase Performance-enhanced Edition. For step-by-step instructions, see Configure a whitelist.
