Question

我正在创建一个Kafka消费者。

使用这篇文章我安装了Zooker和Kafka。 https://dzone.com/articles/running-apache-kafka-on-windows-os

使用此文档我正在配置入站Kafka端点 https://docs.wso2.com/display/EI611/Kafka+Inbound+Protocol

当我尝试部署入站端点时，我收到此错误

如果您需要在没有安全性的情况下配置Kafka，则推荐版本为0.8.1.1。

从Kafka 0.9版开始，他们已经引入了带有SSL和SASL的Kafka安全机制，它将通过JAAS进行配置。因此，在使用WSO2产品（EI，DAS，CEP）配置Kafka时，您需要将此配置文件（jaas.conf）添加到/ repository / conf / identity。

在这种情况下，WSO2产品充当Kafka客户端，jaas.conf中的配置将用于登录kafka服务器。请遵循Kafka安全文档[1]来配置服务器和客户端的安全性。

为SASL / Plaintext配置的jaas.conf文件的示例内容。

KafkaServer {
org.apache.kafka.common.security.plain.PlainLoginModule required
   username="kafka"
   password="kafka-secret"
   user_kafka="kafka-secret"
   user_ibm="ibm-secret";
};

KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
  username="kafka"
  password="kafka-secret";
};

请注意，kafka 0.9仅支持SASL / Kerberos身份验证。请仔细阅读与您的Kafka版本相关的Kafka安全文档并进行正确配置。
