所以我剛剛建立了一個HA環境，我有一個主服務器和一個使用Neo4J嵌入式應用程序的實例與該羣集通話。如果兩個數據庫的狀態都是相同的，那麼一切似乎都有效。Neo4J HA與Neo4J Spatial
但是，如果我從我的從實例中刪除所有數據，並讓它加入集羣，我希望集羣中的數據能夠傳播到從實例中。相反，我看到的是Neo4J空間的錯誤。我的應用程序中有Neo4J空間，服務器插件安裝在主服務器端。
堆棧跟蹤我得到的一個例子：

跨實例確實Neo4j的空間支持複製？或者更具體地說，將空間索引恢復爲第一次加入集羣的新空實例？
這看起來像是一個版本問題。請確保您是Neo4j版本和Spatial擴展版本。 –
所以我使用neo4j 2.2.5和neo4j空間版本0.14-neo4j-2.2.3。我試圖把0.14-neo4j-2.2.5空間放在master和我的應用程序中，但是我得到了同樣的錯誤。這隻有當我有一個空的應用程序加入一個現有的羣集。如果主機和從機都是空的，或者主機和從機都有相同的數據庫，它似乎工作得很好。 – lordmj
我猜這是值得提出的Neo4j空間這個問題：https://github.com/neo4j-contrib/spatial/issues/new –
