leader切换

[Shy-Chen]

3节点raft集群运行过程中 出现了leader切换 日志如下

因为都是在本地启动的服务 应该不是网络问题 这个是因为什么导致leader切换？

[killme2008]

本地服务不代表不会有网络问题，这是两个节点失联了

com.alipay.sofa.jraft.core.NodeImpl#2219◊ 1860768◊ NULL◊ NULL◊ NULL◊ Node <r1/127.0.0.1:8083> steps down when alive nodes don't satisfy quorum, term=3, deadNodes=127.0.0.1:8081,127.0.0.1:8082,

具体还需要看下上下文和其他节点的日志
