我正在嘗試對(duì) KafkaConsumer 使用 kerberos 身份驗(yàn)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(cuò)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(cuò)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.
