做zookeeper clinet客户端开发zookeeper使用如下版本 zk.version3.4.5-cdh5.15.1/zk.version curator-recipes使用3.3.0.会报如下错误Exception in thread main java.lang.NoClassDefFoundError: org/apache/curator/connection/ConnectionHandlingPolicy at org.apache.curator.framework.CuratorFrameworkFactory.builder(CuratorFrameworkFactory.java:77) at org.apache.curator.framework.CuratorFrameworkFactory.newClient(CuratorFrameworkFactory.java:103) at org.apache.curator.framework.CuratorFrameworkFactory.newClient(CuratorFrameworkFactory.java:89) at com.wxx.bigdata.zookeepper.curator.CuratorClient.main(CuratorClient.java:14) Caused by: java.lang.ClassNotFoundException: org.apache.curator.connection.ConnectionHandlingPolicy at java.net.URLClassLoader.findClass(URLClassLoader.java:381) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:335) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 4 more经过了解Curator的版本和zookeeper的版本有对应关系。Curator2.X的吧对于Curator2.X是支持Zookeeper3.4.X的所以如果目前你是Zookeeper3.4.X的版本还是使用Curator2.X的吧比如2.7.0
