我试图弄清楚如何用Hbase 2.0.x或2.1.x插入janusGraph

我在https://github.com/JanusGraph/janusgraph/issues/915中看到，在0.3.1版本中有可能，但默认情况下未启用。

我试图测试它是否在使用hbase表创建过程中卡住了：

线程“主”中的异常java.lang.NoSuchMethodError：org.apache.hadoop.hbase.client.Admin.createTable（Lorg / apache / hadoop / hbase / HTableDescriptor;）V 在org.janusgraph.diskstorage.hbase.HBaseAdmin1_0.createTable（HBaseAdmin1_0.java:117）在org.janusgraph.diskstorage.hbase.HBaseStoreManager.createTable（HBaseStoreManager.java:780）在org.janusgraph.diskstorage.hbase.HBaseStoreManager.ensureTableExists（HBaseStoreManager.java:744）在org.janusgraph.diskstorage.hbase.HBaseStoreManager.getLocalKeyPartition（HBaseStoreManager.java:536）在org.janusgraph.diskstorage.hbase.HBaseStoreManager.getDeployment（HBaseStoreManager.java:375）在org.janusgraph.diskstorage.hbase.HBaseStoreManager.getFeatures（HBaseStoreManager.java:417）在org.janusgraph.graphdb.configuration.GraphDatabaseConfiguration。（GraphDatabaseConfiguration.java:1256）在org.janusgraph.core.JanusGraphFactory.open（JanusGraphFactory.java:160）在org.janusgraph.core.JanusGraphFactory.open（JanusGraphFactory.java:131）在org.janusgraph.core.JanusGraphFactory.open（JanusGraphFactory.java:121）在org.janusgraph.core.JanusGraphFactory $ Builder.open（JanusGraphFactory.java:260）

如何启用Hbase 2.0支持？

这是我的代码示例：

public static void main(String[] args) throws BackendException {
        JanusGraph graph = JanusGraphFactory.build()
                .set("storage.backend", "hbase")
                .set("gremlin.graph", "org.janusgraph.core.JanusGraphFactory")
                .set("storage.hostname", "vmdev")
                .set("cache.db-cache", "true")
                .set("cache.db-cache-clean-wait","20")
                .set("cache.db-cache-time","180000")
                .set("cache.db-cache-size", "0.5").open();
        GraphTraversalSource g = graph.traversal();
        if (g.V().count().next() == 0) {
            tracer.info("empty graph, building DM");
            buildDM(graph);
        }
        System.exit(0);

    }

您是否尝试过使用最新版本？最新版本说明指出，它们支持HBase 2.1 https://docs.janusgraph.org/latest/version-compat.html

大约2.0，我不确定，但是我将对其进行测试。我的同事声称，我们以前曾运行过HBase 2.0，但它确实有效...

具有Hbase 2.0.x和2.1.x的JanusGraph
