一、报错信息

DEBUG org.apache.zookeeper.ClientCnxnSocketNIO - Ignoring exception during shutdown input
java.net.SocketException: Socket is not connectedat sun.nio.ch.Net.translateToSocketException(Net.java:123)at sun.nio.ch.Net.translateException(Net.java:157)at sun.nio.ch.Net.translateException(Net.java:163)at sun.nio.ch.SocketAdaptor.shutdownInput(SocketAdaptor.java:401)at org.apache.zookeeper.ClientCnxnSocketNIO.cleanup(ClientCnxnSocketNIO.java:200)

二、问题描述

在使用java连接zookeeper客户端时，发现连接是成功的，但是操作数据时报错

连接zookeeper客户端代码

public class Test {//此处是机器ip:端口号。多个ip用,隔开private static String connectString = "机器ip:2181";int sessionTimeout = 5000;@org.junit.Testpublic void test() throws IOException {ZooKeeper zooKeeper = new ZooKeeper(connectString, sessionTimeout, new Watcher() {/*** 监听事件* @param event*/@Overridepublic void process(WatchedEvent event) {System.out.println("监听事件"+event);}});System.out.println(zooKeeper);}
}

打印信息——连接成功

State:CONNECTING sessionid:0x0 local:null remoteserver:null lastZxid:0 xid:1 sent:0 recv:0 queuedpkts:0 pendingresp:0 queuedevents:0

操作zookeeper代码

public class Test1 {String connectString = "192.168.75.130:2181,192.168.75.131:2181,192.168.75.132:2181";int sessionTimeout = 5000;ZooKeeper zooKeeper = null;@Beforepublic void test() throws IOException {zooKeeper = new ZooKeeper(connectString, sessionTimeout, new Watcher() {/*** 监听事件* @param event*/@Overridepublic void process(WatchedEvent event) {System.out.println("监听事件" + event);}});
//        System.out.println(zooKeeper);}/*** 创建节点*/@Testpublic void createNode() throws Exception {String path = zooKeeper.create("/apptest" // 节点路径, "HelloZookeeper".getBytes() // 节点的数据, ZooDefs.Ids.OPEN_ACL_UNSAFE // 权限, CreateMode.PERSISTENT // 节点类型);System.out.println(path);}
}

打印信息——报错

DEBUG org.apache.zookeeper.ClientCnxnSocketNIO - Ignoring exception during shutdown input
java.net.SocketException: Socket is not connectedat sun.nio.ch.Net.translateToSocketException(Net.java:123)at sun.nio.ch.Net.translateException(Net.java:157)at sun.nio.ch.Net.translateException(Net.java:163)at sun.nio.ch.SocketAdaptor.shutdownInput(SocketAdaptor.java:401)at org.apache.zookeeper.ClientCnxnSocketNIO.cleanup(ClientCnxnSocketNIO.java:200)

三、原因分析：

服务器zookeeper版本和pom依赖版本不一致导致的

四、解决方案：

将pom依赖版本服务器zookeeper版本

服务器版本查看3.8.2版本：

[root@zookeeper01 lib]# pwd
/opt/zookeeper/lib
[root@zookeeper01 lib]# 
[root@zookeeper01 lib]# ll -r

-rw-r--r--. 1 root root   11358 8月  31 00:20 snappy-java-1.1.10.1.jar_LICENSE.txt

更改pom依赖版本为3.8.2
