Facing Issue while connecting to hbase-0.96.1. #7

Closed a2prn closed 7 years ago

a2prn commented 10 years ago

I am using hadoop-2.2.0 and hbase-0.96.1 on ubuntu-12.04. I have created the sample code to connect to hbase and create tables there.

var Titan = require('titan-node'); var g = new Titan.Gremlin({ loglevel: 'OFF' });

var BaseConfiguration = g.java.import('org.apache.commons.configuration.BaseConfiguration'); var _storageConfObj={'backend':'hbase','hostname':'ip address of hbase','port':'2181','tablename':'titan6'};

    conf = new BaseConfiguration();
    conf.setPropertySync("storage.backend",_storageConfObj.backend);
    conf.setPropertySync("storage.tablename",_storageConfObj.tablename);

var TitanFactory = g.java.import('com.thinkaurelius.titan.core.TitanFactory'); var titanGaraph = TitanFactory.openSync(conf);

g.SetGraph(titanGraph);

when I run the code using node,

node ./test.js

I face below error:
