Trying to understand error "Wrong request type 9".

[Eric Rini]

So I am using this https://github.com/SOHU-Co/kafka-node client library
(possibly the only v0.8 node.js library that supports a high level consumer
and has some basic docs). When it connects to the broker, an error like
this appears in the console.

[2014-01-28 23:42:30,423] ERROR Closing socket for /192.168.1.102 because
of error (kafka.network.Processor)

kafka.common.KafkaException: Wrong request type 9

at kafka.api.RequestKeys$.deserializerForKey(RequestKeys.scala:53)

at kafka.network.RequestChannel$Request.<init>(RequestChannel.scala:49)

at kafka.network.Processor.read(SocketServer.scala:353)

at kafka.network.Processor.run(SocketServer.scala:245)

at java.lang.Thread.run(Thread.java:722)


Can someone shed some light on what this means? Here's the node.js code...
pretty boilerplate.


var kafka = require('kafka-node');

var kafkaClient = new kafka.Client('localhost:2181', 'test-consumer');

var topics = [

    { topic: 'test3', partition: 0 }

];

var kafkaConsumer = new kafka.Consumer(kafkaClient, topics, {

    autoCommit: false

});

kafkaConsumer.on('message', function (message) {

    console.log('MESSAGE');

    console.log(message);

});

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

    console.log('ERROR');

    console.error(err);

});

kafkaConsumer.on('offsetOutOfRange', function (err) {

    console.log(err);

});
