Question

我正在使用node.js v6 LTS和npm jdbc包连接到hortonworks上的Apache phoenix。我的代码如下： -

var JDBC = require('jdbc');
var jinst = require('jdbc/lib/jinst');

var jar1='/home/ashish/seed-project-phoenix/public/drivers/phoenix-core-4.7.0.2.5.6.0-40.jar';
var jar2='/home/ashish/seed-project-phoenix/public/drivers/phoenix-queryserver-client-4.7.0.2.5.6.0-40.jar';
var jar3='/home/ashish/seed-project-phoenix/public/drivers/hbase-client-1.1.2.2.5.6.0-40.jar';

if (!jinst.isJvmCreated()) {
  // Add all java options required by your project here.  You get one 
  //chance to setup the options before the first java call.
        jinst.addOption("-Xrs");
  // Add all jar files required by your project here.  You get one chance to
  // setup the classpath before the first java call.
        jinst.setupClasspath([jar1,jar2,jar3]); // adding jars
    }

var config = {
    url:'jdbc:phoenix:ZK1,ZK2,ZK3:2181:/hbase-unsecure',
    drivername: 'org.apache.phoenix.jdbc.PhoenixDriver'
};

var phoenixHbase = new JDBC(config);
phoenixHbase.initialize(function(err) {
     if (err) {
        console.log(err);
    }
    else{
        console.log("connected to Apache phoenix ...");
    }
});

但我收到以下错误： -

根据我的说法，连接字符串应该没有问题，并且已根据版本添加了所有jar文件。

凤凰版： - 4.7.0.2.5.6.0-40 Hbase版本： - 1.1.2.2.5.6.0-40

如果有人做过类似的事情，请给出一些指示。
