 In ByConity, there are three methods of mutual discovery between components. The `mode` tag is used to specify the method, with three modes: `local`, `dns`, and `consul`. In `local` mode, users need to specify the IP addresses or hostnames of all components in this configuration file by replacing the placeholder `{your_xxx_address}` (for example, `{your_server_address}`), which should be the component's actual IP address, such as `10.0.2.72`.
 
+In `local` mode, the specific address of a service is mainly obtained between services via `host` (`service_discovery > xxx > node[] > host`).
+Therefore, it is important to make sure that the value of this item (e.g. an IP or domain name that can be used for external access) can be used for service discovery.
+
 For the `hdfs_nnproxy` tag, it includes the address of the HDFS namenode.

 在 ByConity 中，组件之间有三种相互发现的方式。`mode` 标签用于指定方式，有三种模式：`local`、`dns` 和 `consul`。
 在 `local` 模式下，用户需要在此配置文件中指定所有组件的 IP 地址或主机名，通过替换占位符 `{your_xxx_address}`（例如 `{your_server_address}`），该占位符实际上是组件的 IP 地址，例如 `10.0.2.72`。
 
+在 `local` 模式下，服务之间主要通过 `host` (`service_discovery > xxx > node[] > host`) 来获取某个服务的具体地址。
+因此，请务必确保该项的值（比如可用于外部访问的 IP 或者域名）能够用于服务发现。

 对于 `hdfs_nnproxy` 标签，包含 HDFS 的 namenode 地址。
