Yang Wang commented on FLINK-26356:
-----------------------------------

I think we could always use the {{<cluster-id>-rest.<namespace>}} to access the 
Flink rest server no matter the HA is enabled or not. Right?

> The clusterClient is built as below. The config is mixed up with the 
> FlinkDeploymentSpec and local default config. 
> {code:java}
> final int port = config.getInteger(RestOptions.PORT);
> final String host =
>         config.getString(
>                 RestOptions.ADDRESS, String.format("%s-rest.%s", clusterId, 
> namespace));
> final String restServerAddress = String.format("http://%s:%s";, host, port); 
> {code}
> But the {{RestOptions.ADDRESS}} is generated at the entrypoint when the HA is 
> enabled, so the option can not obtain from the FlinkDeploymentSpec.
> Furthermore, the default rest url is not suitable for all the service type. I 
> think we should extract the rest endpoint from the Flink external service.
