Kafka 连接中的 ACL 配置不起作用 [英] ACL configuration in Kafka connect is not working

问题描述

我为 3 节点 Kafka 集群设置了 ACL，并且能够通过生产者控制台和消费者控制台发送和接收主题.现在我想用 ACL 配置 Kafka 连接.我尝试使用 SASL_PLAINTEXT 组合，并在 connect.log 文件中显示以下错误.它没有从源表同步到主题，请帮助我缺少任何配置.

I setup ACL for 3 node Kafka cluster and able to send and receive for a topic through producer console and consumer console. Now I want to configure Kafka connect with ACL. I tried with SASL_PLAINTEXT combinations and in connect.log file it shows the following error. it is not syncing to from source table to topic, please help where I am missing any configuration.

我按照以下文件进行配置.我已经在 jaas.conf 文件中提到了用户并设置到环境中.

推荐答案

您需要将以下属性添加到您的connect-distributed.properties:

You need to add the following properties to your connect-distributed.properties:

sasl.mechanism=PLAIN
security.protocol=SASL_PLAINTEXT

sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required \
  username="connect" \
  password="connect-secret";

producer.sasl.mechanism=PLAIN
producer.security.protocol=SASL_PLAINTEXT
producer.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required \
  username="connect" \
  password="connect-secret";

consumer.sasl.mechanism=PLAIN
consumer.security.protocol=SASL_PLAINTEXT
consumer.sasl.jaas.config=org.apache.kafka.common.security.plain.PlainLoginModule required \
  username="connect" \
  password="connect-secret";
