我是Titan graph-Db的新手，使用（版本0.5.4）
已使用以下命令使用hbase配置并将其加载到图形示例：
graph = TitanFactory.open('conf/titan-hbase.properties')
但使用后：
schema = graph.openManagement()
出现以下错误：

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