node-cassandra-cql :: Error - Socket was closed

[iflairBhavin]

Respected Sir,

When i try to connect in my local machine (ubuntu 10.04) i am getting below error. Can you please give me any solution to fix that. Thanks in advance for your help.

My Code:

var loopback = require('loopback');
var app = loopback();
var cql = require('node-cassandra-cql');
var client = new cql.Client({hosts: ['192.168.1.40:9042'], keyspace: 'catalog'});
client.connect(function established(err){if (err) console.log(err);
else console.log('Connection with Cassandra established');});
app.listen(9042);

Getting Error :

{ [PoolConnectionError]
name: 'PoolConnectionError',
info: 'Represents a error while trying to connect the pool, all the connections failed.',
individualErrors:
[ { [Error: Socket was closed]
message: 'Socket was closed',
info: 'Cassandra Driver Error',
isServerUnhealthy: true } ] }
