私はノードのjs カサンドラのバージョンを使用してカサンドラインスタンスへの接続にタイムアウトを受けています:3.9 ノードJS:v6.9.1 私はこのドライバを使用して接続しています:https://github.com/datastax/nodejs-driverここNode.jsのカサンドラ接続タイムアウト
私のコードスニペットです:
const express = require('express');
const cassandra = require('cassandra-driver');
const async = require('async');
// Constants
const PORT = 8080;
const CASSANDRA_PORT = process.env['CASSANDRA_PORT'];
const CASSANDRA_PATH = '127.0.0.1';
// App
const app = express();
app.set('view engine', 'pug');
app.set('views', './views');
var client = new cassandra.Client({contactPoints: [CASSANDRA_PATH], protocolOptions: {port: CASSANDRA_PORT}});
client.on('log', function(level, className, message, furtherInfo) {
console.log('log event: %s -- %s', level, message);
});
client.connect(function (e, m) {
console.log(e);
console.log(m);
});

はFYI、キースペースが作成されますあらかじめ。 サーバの起動中にこのタイムアウト例外を回避するにはどうすればよいですか?
ありがとう、9042ポートの確立は接続で私を助けました! –
