我在分布式模式下使用了orientdb，但我遇到了一些问题..
我尝试过版本2.0.2,2.0.4和2.1-SHAPSHOT。
使用带有Tinkerpop库的java客户端，尝试插入记录时，数据库会抛出异常：
com.orientechnologies.common.exception.OException: Cannot find best cluster for class 'MYCLASS' on server 'node1'.
我注意到的另一个错误是：
Cannot route READ_RECORD operation for #-1:-3 to the distributed node
java.lang.IllegalArgumentException: Cannot read record #-1:-3 since the position is invalid in database 'mydb'
非常感谢
修改
我注意到它有时会起作用，我想我在哪种情况下找到了：
使用dserver.sh启动第一个节点，然后使用dserver.sh运行第二个节点。
从我的java Tinkerpop客户端，如果我将连接设置为第一个节点，则无法使用“无法找到最佳群集”，但如果我将其配置为连接到第二个节点..它可以工作！
如果我在第一个节点之前启动第二个节点，我的客户端必须配置为指向第一个节点才能使其正常工作！
希望有所帮助

使用2.0.5似乎有效，但现在我在顶点删除过程中遇到了另一个问题。
