Package org.apache.hadoop.registry.client.impl.zk Description

Core Zookeeper support.

This package contains the low-level bindings to Curator and Zookeeper, including everything related to registry security.

The class CuratorService is a YARN service which offers access to a Zookeeper instance via Apache Curator.

The RegistrySecurity implements the security support in the registry, though a set of static methods and as a YARN service.

To work with ZK, system properties need to be set before invoking some operations/instantiating some objects. The definitions of these are kept in ZookeeperConfigOptions.
