/**
* Core Zookeeper support.
* <p>
* This package contains the low-level bindings to Curator and Zookeeper,
* including everything related to registry security.
* <p>
* The class {@link org.apache.hadoop.registry.client.impl.zk.CuratorService}
* is a YARN service which offers access to a Zookeeper instance via
* Apache Curator.
* <p>
* The {@link org.apache.hadoop.registry.client.impl.zk.RegistrySecurity}
* implements the security support in the registry, though a set of
* static methods and as a YARN service.
* <p>
* To work with ZK, system properties need to be set before invoking
* some operations/instantiating some objects. The definitions of these
* are kept in {@link org.apache.hadoop.registry.client.impl.zk.ZookeeperConfigOptions}.
