这段日志是Zookeeper启动时输出的，它显示了Zookeeper在读取配置文件时遇到了问题。具体来说，它指出了myid文件缺失，而这个文件是Zookeeper用来标识节点编号的文件。因此，Zookeeper无法根据配置文件正常启动。要解决这个问题，需要检查配置文件中是否正确设置了myid文件的路径，并且确保在该路径下存在myid文件。

Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.server.quorum.QuorumPeerMain

这个异常信息表明Java程序无法找到org.apache.zookeeper.server.quorum.QuorumPeerMain类。这可能是由于以下原因之一导致的：

1.缺少zookeeper依赖项，需要将zookeeper jar文件添加到类路径中。

2.类路径中的zookeeper jar文件版本与程序代码不兼容，需要更新zookeeper jar文件。

以下是添加zookeeper依赖项的示例代码：

<dependency>
    <groupId>org.apache.zookeeper</groupId>
    <artifactId>zookeeper</artifactId>
    <version>3.6.2</version>
</dependency>
