Apache Curator 2.4.0 发布，该版本主要是 bug 修复，包括：
[CURATOR-53] - PersistentEphemeralNode does not work when ZK server are not available when the node is started
[CURATOR-58] - ACLs support for ZKPaths.mkdirs()
[CURATOR-72] - Background operations don't wait for connection timeout
[CURATOR-75] - InterProcessSemaphoreV2 does not register changes to SharedCountReader while blocking
[CURATOR-81] - Service Discovery InstanceCleanup cleans up DYNAMIC registration
[CURATOR-85] - curator-client ConnectionState uses deprecated Closeables method
zookeeper 的客户端调用过于复杂，Apache Curator 就是为了简化zookeeper客户端调用而生，利用它，可以更好的使用zookeeper。
