异常运行 kafka-console-producer.sh (0.8.1.1) [英] Exception running kafka-console-producer.sh (0.8.1.1)

问题描述

我正在试用 kafka-console-producer.sh.我在控制台上输入一些东西并按回车键，我会像这样在控制台上获得大量的堆栈跟踪.感谢任何指点.

I am trying out the kafka-console-producer.sh. I type something to the console and hit enter and I get tons of stack traces to the console like this. Appreciate any pointers.

启动生产者的命令是:

./bin/kafka-console-producer.sh --broker-list localhost:2181 --topic test

然后我输入一些字符串并按回车键并在控制台中看到以下内容.

Then I type some string and hit enter and see the following in the console.

我也在 zookeeper 控制台上看到警告:

I see a warning on the zookeeper console as well:

WARN Exception causing close of session 0x0 due to java.io.EOFException (org.apache.zookeeper.server.NIOServerCnxn)    

我使用以下内容来设置我的主题:

I used the following to setup my topic:

./bin/kafka-topics.sh --create --zookeeper localhost:2181 --partitions 1 --replication-factor 1 --topic test

并且我可以列出我的主题:

and I am able to list my topic:

./bin/kafka-topics.sh --list --zookeeper localhost:2181

推荐答案

您的 broker-list 参数指向 Zookeeper 而不是实际的 broker.正确的用法是:

Your broker-list argument is pointing to Zookeeper instead of the actual broker. The proper usage would be:

./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

假设您的代理在端口 9092(默认)上运行.

assuming your broker runs on port 9092 (default).
