a strange etcd cluster, data inconsistent

[yourlovemyall]

I create a cluster of etcd， now etcd1 has three keys data， but etcd2（leader） and etcd3 has one key data；
only differenet operation ： I stop the etcd process manually on etcd1 node，and modify the etcd cluster data when etcd1 is down， then I not clean the etcd1 node data dir and restart the etcd process， first I found data the same ， but now the data different ；

This operation may cause this exception？

What about WAL logs? If I understand you right, you have to delete WAL logs as well.
