我正在嘗試對 KafkaConsumer 使用 kerberos 身份驗證。為此，我添加了以下屬性。 props.put("security.protocol", "SASL_PLAINTEXT"); // Setting this means we try to look in jaas.conf props.put("sasl.kerberos.service.name", "kafka");但是，我收到一條錯誤消息：java.lang.IllegalArgumentException: Could not find a 'KafkaClient' entry in the JAAS configuration. System property 'java.security.auth.login.config' is /Users/jhutc/projects/molly/Monitor-Lizard-API/out/production/resources/hive_config/local/jaas.conf完整錯誤：Caused by: org.apache.kafka.common.KafkaException: Failed to construct kafka consumerat org.apache.kafka.clients.consumer.KafkaConsumer.<init>(KafkaConsumer.java:799) ~[kafka-clients-2.0.0.jar:?]at org.apache.kafka.clients.consumer.KafkaConsumer.<init>(KafkaConsumer.java:615) ~[kafka-clients-2.0.0.jar:?]at org.apache.kafka.clients.consumer.KafkaConsumer.<init>(KafkaConsumer.java:596) ~[kafka-clients-2.0.0.jar:?]at com.xxx.xx.moli.data.KafkaDataHelper.getConsumer(KafkaDataHelper.java:293) ~[classes/:?]... 53 moreCaused by: java.lang.IllegalArgumentException: Could not find a 'KafkaClient' entry in the JAAS configuration.

JAAS 文件的準確語法可能很難正確掌握。每個 LoginModule 項之后以及每個塊之后都需要分號。principal="[email protected]"所以你可能在塊后面缺少一個分號KafkaClient。
但是，從 Kafka 0.10.2 開始，使用該sasl.jaas.config設置來配置客戶端以使用 SASL 變得更加容易。
例如：
props.put("sasl.jaas.config", "com.sun.security.auth.module.Krb5LoginModule required " +
? ? "useKeyTab=true " +
? ? "storeKey=true " +
? ? "keyTab=\"src/main/resources/hive_config/local/jhutc.keytab\" " +
? ? "principal=\"[email protected]\";");
