ZooKeeper是用于维护配置信息，命名，提供分布式同步和提供组服务的集中式服务。 所有这些类型的服务都以分布式应用程序以某种形式或另一种形式使用。 每次实施时，都有大量的工作要去解决那些不可避免的错误和竞态条件。 由于实施这些服务的难度很大，应用程序最初通常会跳过他们，这使得它们在变化存在时变脆，难以管理。 即使正确完成，这些服务的不同实现也会导致应用程序部署时的管理复杂性。

Apache ZooKeeper是开发和维护开放源代码服务器的一种努力，可实现高度可靠的分布式协调。(Apache ZooKeeper is an effort to develop and maintain an open-source server which enables highly reliable distributed coordination.)
