What you expected to happen

1、EtcdMetadataReport unrealized registerServiceAppMapping method returns false by default. 2、Nacos and zookeeper implement this method

Anything else

No response

Are you willing to submit a pull request to fix on your own?

2.x has been EOL and may be incompatible with dubbo 3.2

You can try the new version of dubbo-metadata-report-etcd, the registerServiceAppMapping method may support in the future version.

    <groupId>org.apache.dubbo.extensions</groupId>
    <artifactId>dubbo-metadata-report-etcd</artifactId>
    <version>3.2.0</version>
