Jian He commented on YARN-6413: ------------------------------- bq. I did not remove any methods, I just didn't add the ones that exist in yarn-native-services but not trunk. I thought doing so would probably cause more conflicts than not. looks like RegistryUtils#extractServiceRecords is removed. Do you mind change RegistryDNSServer to use the new methods ? (i.e. make this patch compile with yarn-native-services branch) bq. My understanding was that DNS went through ZK directly without going through the interface, so it wouldn't be affected by the service records setting up the path differently. I can change the path construction back for the ZK impl if it needs that. The DNS today depends on the ZK path layout to reconstruct the service record. So changing the zk path will break DNS. > Decouple Yarn Registry API from ZK > ---------------------------------- > > Key: YARN-6413 > URL: https://issues.apache.org/jira/browse/YARN-6413 > Project: Hadoop YARN > Issue Type: Improvement > Components: amrmproxy, api, resourcemanager > Reporter: Ellen Hui > Assignee: Ellen Hui > Attachments: 0001-Registry-API-v2.patch, 0002-Registry-API-v2.patch > > > Right now the Yarn Registry API (defined in the RegistryOperations interface) > is a very thin layer over Zookeeper.
