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.
