所以我刚刚建立了一个HA环境，我有一个主服务器和一个使用Neo4J嵌入式应用程序的实例与该群集通话。如果两个数据库的状态都是相同的，那么一切似乎都有效。Neo4J HA与Neo4J Spatial
但是，如果我从我的从实例中删除所有数据，并让它加入集群，我希望集群中的数据能够传播到从实例中。相反，我看到的是Neo4J空间的错误。我的应用程序中有Neo4J空间，服务器插件安装在主服务器端。
堆栈跟踪我得到的一个例子：

跨实例确实Neo4j的空间支持复制？或者更具体地说，将空间索引恢复为第一次加入集群的新空实例？
这看起来像是一个版本问题。请确保您是Neo4j版本和Spatial扩展版本。 –
所以我使用neo4j 2.2.5和neo4j空间版本0.14-neo4j-2.2.3。我试图把0.14-neo4j-2.2.5空间放在master和我的应用程序中，但是我得到了同样的错误。这只有当我有一个空的应用程序加入一个现有的群集。如果主机和从机都是空的，或者主机和从机都有相同的数据库，它似乎工作得很好。 – lordmj
我猜这是值得提出的Neo4j空间这个问题：https://github.com/neo4j-contrib/spatial/issues/new –
