当我试图使用命令“zkServer stop“停止ZooKeeper时，得到了以下结果：

call "C:\Program Files\Java\jdk1.8.0_121"\bin\java "-Dzookeeper.log.dir=C:\zookeeper-3.4.10\bin\.." "-Dzookeeper.root.logger=INFO,CONSOLE" -cp "C:\zookeeper-3.4.10\bin\..\build\classes;C:\zookeeper-3.4.10\bin\..\build\lib\*;C:\zookeeper-3.4.10\bin\..\*;C:\zookeeper-3.4.10\bin\..\lib\*;C:\zookeeper-3.4.10\bin\..\conf" org.apache.zookeeper.server.quorum.QuorumPeerMain "C:\zookeeper-3.4.10\bin\..\conf\zoo.cfg" stop

输出量：

我确信我已经启动了Zookeeper，因为当我试图启动一个新的时，它显示“java.net.BindException: Address already in use: bind“
另一个奇怪的问题是，我在Windows服务列表中找不到Zookeeper。然而，当我试图通过netstat -and显示Windows PowerShell中的所有端口使用情况时，我发现2181正在使用中：
