Question:
Can't connect to Cosmos to query Hive witch Python or Node.js client

Description:
I am actually trying to develop a simple node.js client which can be used to query my Hive table on the Cosmos table .

I first try to use this implememtation for Hive using node.js :
https://github.com/wdavidw/node-thrift-hive. My code is the following :

var router = express.Router();
var request = require('request');
var _ = require('lodash');

var hive = require('thrift-hive');
// Client connection
var client = hive.createClient({
version: '0.7.1-cdh3u3',
server: '130.206.80.46',
port: 10000,
timeout: 1000
});
// Execute call

router.route('/')
.get(function(req, res, next) {

client.execute('use default', function(err){
// Query call
client.query('select * from interserre')
.on('row', function(database)

)
.on('error', function(err)

)
.on('end', function()

);
});

})

module.exports = router;

I get this error :

events.js:85
throw er; // Unhandled 'error' event
^
Error: connect ECONNREFUSED
at exports._errnoException (util.js:746:11)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1010:19)

After that I tried to use the Python example (provided by the documentation just to run a simple test.
http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/BigData_Analysis_-_User_and_Programmer_Guide#Python

I could'nt even connect to the server.

Could not connect to 130.206.80.46:10000

The python was just a test . I'm actually doing a Hackaton and was planning to use Node.js to query the data I have. Where do you think the problem come from? The module? The Cosmos Portal?

I think the problem come from the fact that we don't provide any information that allow us to connect to the Cosmos portal . With Thrift there is no way to put your credentials. The server can't identify you're a real Cosmos user and reject your connection.
