一个两节点分布式 OrientDB 系统，嵌入式模式，使用 TCP-IP 进行节点发现。该类event在四个集群上分片。重新启动一个节点后，该节点上恰好有一半的插入失败并显示错误消息：
INFO Local node 'orientdb-lab-node2' is not the owner for cluster 'event_1' (it is 'orientdb-lab-node1'). Reloading distributed configuration for database 'test-db' [ODistributedStorage]
和堆栈跟踪：
com.orientechnologies.orient.server.distributed.ODistributedConfigurationChangedException: Local node 'orientdb-lab-node2' is not the owner for cluster 'event_1' (it is 'orientdb-lab-node1')

这是从 node1 看集群配置的样子：
节点 1 和 2 正在运行，每个节点上 10 次插入
