zookeeper 的节点删除不了？

java 客户端用的 curator 加了监听之后节点删除不了 修改依赖到 2.4.2 就可以 代码如下

 <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-framewor</artifactId> <version>4.2.0</version> </dependency> <dependency> <groupId>org.apache.curator</groupId> <artifactId>curator-recipes</artifactId> <version>4.2.0</version> </dependency> 

public static void main(String[] args) throws Exception { CuratorFramework client = CuratorFrameworkFactory .builder() .connectString("192.168.215.128:2181") .sessionTimeoutMs(5000) .retryPolicy(new ExponentialBackoffRetry(1000, 3)) .build(); client.start(); String path = "/zk-book"; PathChildrenCache cache = new PathChildrenCache(client, path, true); cache.start(PathChildrenCache.StartMode.POST_INITIALIZED_EVENT); cache.getListenable().addListener((client1, event) -> { switch (event.getType()) { case CHILD_ADDED: System.out.println("CHILD_ADDED," + event.getData().getPath()); break; case CHILD_UPDATED: System.out.println("CHILD_UPDATED," + event.getData().getPath()); break; case CHILD_REMOVED: System.out.println("CHILD_REMOVED," + event.getData().getPath()); break; default: break; } }); client.create() .withMode(CreateMode.PERSISTENT) .forPath(path); Thread.sleep(2000); client.delete().deletingChildrenIfNeeded().forPath(path); System.out.println("done"); Thread.sleep(Integer.MAX_VALUE); }
