[jira] [Created] (YARN-6413) Decouple Yarn Registry API from ZK

Ellen Hui created YARN-6413:
-------------------------------

             Summary: 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: Jian He


Right now the Yarn Registry API (defined in the RegistryOperations interface) is a very thin layer over Zookeeper. This jira proposes changing the interface to abstract away the implementation details so that we can write a FS-based implementation of the registry service, which will be used to support AMRMProxy HA.

The new interface will use register/delete/resolve APIs instead of Zookeeper-specific operations like mknode.
