问无法连接到Hbase

EN

我下载了Janusgraph，解压缩它，并试图通过gremlin连接到它。我想使用HBase作为存储后端。

我运行了以下命令：

JanusGraph g = JanusGraphFactory.build().set("storage.backend", "hbase").set("storage.hostname", [SERVERNAME]).set("storage.port", "2181").set("storage.hbase.ext.zookeeper.znode.parent", "/hbase-secure").set("storage.hbase.table", "test").open();

也尝试过：

JanusGraph g = JanusGraphFactory.build().set("storage.backend","hbase").set("storage.hostname,[SERVERNAME]).set("storage.hbase.ext.zookeeper.znode.parent", "/hbasesecure").set("storage.hbase.table", "test").set("cache.db-cache-time","180000").set("cache.db-cache-size","0.5").set("cache.db-cache-cleanwait","20").set("cache.db-cache", "true").open();

得到了下面的例外。知道我做错了什么吗？
