我需要先开始哪个Zookeeper合奏？

编程问答 2022-06-10

问题描述

我创建了3个zookeeper实例，并在所有3个实例中进行了如下配置，并在myid文件中分别设置了相应的id： 

server.1=localhost:2888:3888
server.2=localhost:2881:3881
server.3=localhost:2882:3882

现在，我应该首先启动哪个实例？启动server.1时，我将进入以下位置：

 WARN  [QuorumConnectionThread-[myid=1]-1:QuorumCnxManager@400] - Cannot open channel to 2 at election address localhost/127.0.0.1:3881
