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.
