在分布式 OrientDB 集群中重新启动节点后插入（JavaAPI）失败

Question

一个两节点的分布式OrientDB系统，嵌入式模式，使用TCP-IP进行节点发现。 class event 在四个集群上进行分片。重新启动一个节点后，该节点上恰好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')

这是节点 1 的集群配置：

节点 1 和 2 运行，每个节点上有 10 个插入

感谢任何提示或建议。谢谢。

这个问题已经在 OrientDB 2.2.13-SNAPSHOT 上解决了，所以很快就会在发布版本中解决：https://github.com/orientechnologies/orientdb/issues/6897
