在使用Titan图形数据库的openManagement()方法时出现错误

Question

我是一个新手，正在使用Titan图数据库（版本0.5.4）

使用以下命令使用hbase配置并将其加载到图实例中：

graph = TitanFactory.open('conf/titan-hbase.properties')

但是在使用以下命令后：

schema = graph.openManagement()

我遇到了以下错误：

No signature of method: groovy.lang.MissingMethodException.openManagement() is applicable for argument types: () values: []
Display stack trace? [yN] y
groovy.lang.MissingMethodException: No signature of method: groovy.lang.MissingMethodException.openManagement() is applicable for argument types: () values: []

Answer 1

在Titan 0.5.4中访问模式，请使用此方法

mgmt = graph.getManagementSystem();

这里记录了Titan 0.5.4文档中的使用方法。 http://s3.thinkaurelius.com/docs/titan/0.5.4/schema.html

你试图使用的方法来自Titan 0.9。
