我正在尝试使用Apache Flink从针对Kafka主题的自定义反序列化器连接到Hortonworks Schema Registry。
通过在Kafka使用者上设置 sasl.jaas.config 属性，我可以从受保护的Kafka中读取消息。但是，当我添加一个使用Hortonworks Schema Registry获取反序列化模式的自定义反序列化器时，需要使用401 HTTP Code：Authentication进行服务响应。我已在此服务上启用Kerberos。
我尝试过的事情：
在反序列化器实现上设置java.security.auth.login.config：
System.setProperty("java.security.auth.login.config", "/path/to/jaas.conf");
使用动态Java选项启动应用程序：
flink run [...] -yD env.java.opts="-Djava.security.auth.login.config=/path/to/jaas.conf" myApplicatio.jar
在 flink-conf.yaml 中设置env.java.opts：
env.java.opts: -Djava.security.auth.login.config=/path/to/jaas.conf
这些选项都不适合我。
要针对HW Schema注册表进行身份验证的jaas.conf的内容为：
RegistryClient {
com.sun.security.auth.module.Krb5LoginModule required
principal="flink@mydomain.com"
keytab="/etc/security/keytabs/flink.keytab"
useKeytab=true
useTicketCache=true
renewTicket=true
serviceName="flink";
};
有人可以帮忙吗？
更新：我希望服务器中缺少某些东西，因为curl请求在Spenego协商中显示内部服务器错误，服务器日志上的回溯是：
