我是新来的Zookeeper编程。我正在尝试使用zookeeper实现生成使用者队列。初始化队列时出现异常。在我的zookeeper中，只有根条目是[zookeeper]。
我正在尝试执行给定的代码。http://zookeeper.apache.org/doc/r3.3.3/zookeepertutorial.html#sc_producerconsumerqueues （不在此处粘贴代码以保持帖子整洁）
例外情况：

org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /app1
at org.apache.zookeeper.KeeperException.create(KeeperException.java:111)
at org.apache.zookeeper.KeeperException.create(KeeperException.java:51)
at org.apache.zookeeper.ZooKeeper.create(ZooKeeper.java:783)
at Queue.<init>(Queue.java:27)
at Queue.main(Queue.java:90)

Can any one advice me on  this?

Thanks
