在集群上集成JanusGraph和HBase

标签: hbase janusgraph

我是BigData的新手。现在我正在尝试将JanusGraph与HBase集成为后端。为此,我使用gremlin控制台。在这个控制台中我写道:

JanusGraph graph = JanusGraphFactory.build().set("storage.backend", "hbase").open();

但是我收到了一个错误:

gremlin> JanusGraph graph = JanusGraphFactory.build().set("storage.backend", "hbase").open();

我不明白为什么会出现这个错误。 hbase的配置文件:

答案 0 :(得分:0)

以下代码对我有用

Builder config = JanusGraphFactory.build();
config.set("storage.hbase.table", "student_table");
config.set("storage.backend", "hbase");
config.set("storage.hostname", "10.20.30.40");    
JanusGraph graph = config.open();

只有在我不使用弹性搜索时才有效。
