Kafka客户端应用程序的临时kerberos身份验证失败

Question

我使用的是最新版本的kafka，在通过SASL_PLAINTEXT将我的消费者/生产者(控制台(客户端连接到kafka broker时暂时面临问题。

这是我的jaas配置文件

KafkaClient {
com.sun.security.auth.module.Krb5LoginModule required
useTicketCache=true;
};

以下是我传递的java属性：

-Djavax.security.auth.useSubjectCredsOnly=false
-Dsecurity.protocol=SASL_PLAINTEXT
-Dsasl.kerberos.service.name=HTTP
-Dsasl.mechanism=GSSAPI

这是我得到的例外：

Caused by: org.apache.kafka.common.KafkaException: javax.security.auth.login.LoginException: Could not login: the client is being asked for a password, but the Kafka client code does not currently support obtaining a password from the user. not available to garner  authentication information from the user

有人能帮忙吗。

Answer 1

主体和keytab。

参见https://kafka.apache.org/documentation/#security_sasl_kerberos

Answer 2

我想建议你的几个选择，

1. 列出当前兑现keytab中的所有原则，并检查它们是否正确。

2. 如果您试图使用KAFKA以外的任何原理对主题进行任何更改，则该操作将失败。Set-Dasl.kerberos.service.name=kafka

3. 尝试设置

   export KAFKA_OPTS="-Djava.security.auth.login.config=/path/to/jaas.conf -Djava.security.krb5.conf=/etc/krb5.conf -Dsun.security.krb5.debug=true"

4. 如果您使用控制台生产者/消费者，则需要提供生产者配置/消费者配置。在producter.properties或consumer.properties.中配置以下属性

   security.protocol=SASL_PLAINTEXT (or SASL_SSL) sasl.mechanism=GSSAPI (or PLAIN)

   对控制台使用者使用如下命令

   kafka-console-consumer --bootstrap-server host:9092 --consumer.config /path/to/consumer.properties --topic Topic

希望这会有所帮助：(
