Could not find a 'KafkaClient' entry in the JAAS configuration. System property

Could not find a ‘KafkaClient’ entry in the JAAS configuratio n. System property ‘java.security.auth.login.config’ is System.setProperty(“java.security.auth.login.config”, jaasPath); pro.put(“sasl.jaas.config”, “com.sun.security.auth.module.Krb5LoginModule required " + 表示如果同时设置了这两个，则启用sasl.jaas.config。所以需要检查是哪个生效了，
