hadoop和neo4j之间的连接

Question

我正在尝试在hadoop和neo4j之间建立连接，这样我就可以导入我的图并将其存储到neo4j中。我找到了这个代码，但它给了我错误，任何人都可以帮助我

这是错误Exception in thread "main" java.lang.NoClassDefFoundError: org/neo4j/io/fs/FileSystemAbstraction at Neo4jMassiveInsertion.startup(Neo4jMassiveInsertion.java:55) at Neo4jMassiveInsertion.main(Neo4jMassiveInsertion.java:41)
