环境详细信息

centos7、独立openwhisk

问题描述

我计划在openwhisk中向kafka发送一条消息，数据流流程是：wsk cli->openwhisk action->kafka console consume。
但在这个过程中会出现间歇性故障，如：我发送“test01”~“test06”，只得到“test02”、“test04”、“test06”。
根据日志，失败的原因是超时。
这是我的动作脚本：

// js
const kafka = require('kafka-node');

const Producer = kafka.Producer;
const client = new kafka.KafkaClient({
    kafkaHost: "192.168.68.132:3093"
});

const producer = new Producer(client);

function main(actionObj) {
    var message = JSON.stringify(actionObj);
    const payloads = [
        {
            topic: 'beforeReductionTopic',
            messages: message,
            partition: 0
        }
    ];
    return new Promise(function (resolve, reject) {
        producer
        .on('ready', () => {
            producer.send(payloads, function (err, data) {
                if (err) {
                    console.log("++++++ producer err: ", err);
                    return reject(err);
                } else {
                    console.log("++++++ producer data: ", data);
                    return resolve(data);
                }
            });
        })
        .on("error", err => {
            console.error(err);
            return reject(err);
        });
    });
}

exports.main = main;

根据日志，这是“动作开发者错误”。
我用下面的代码来测试动作脚本，Kafka可以接收所有的消息。

const action = require("./openwhisk-kafka.js");
for(let i = 0; i < 3; i++) {
    action.main("ccc");
}

我不知道如何修改动作脚本。
