具有 kerberos 的 Kafka Java 生产者

在 kerberos 环境中向 kafka 主题发送消息时出现错误。我们在 hdp 2.3 上有集群

我跟着这个http://henning.kropponline.de/2016/02/21/secure-kafka-java- Producer-with-kerberos/

但是为了发送消息，我必须首先显式执行 kinit，然后只有我才能将消息发送到 kafka 主题。 我尝试通过 java 类进行编织，但这也不起作用。 PFB代码：

package com.ct.test.kafka;

import java.util.Date;
import java.util.Properties;
import java.util.Random;

import kafka.javaapi.producer.Producer;
import kafka.producer.KeyedMessage;
import kafka.producer.ProducerConfig;

public class TestProducer {

    public static void main(String[] args) {

        String principalName = "ctadmin";
        String keyTabPath = "/etc/security/keytabs/ctadmin.keytab";
        boolean authStatus = CTSecurityUtil.loginUserFromKeytab(principalName, keyTabPath);

        if (!authStatus) {
            System.out.println("Authntication fails, try something else  "  + authStatus);
        } else {
            System.out.println("Authntication successfull " + authStatus);
        }

        System.setProperty("java.security.krb5.conf", "/etc/krb5.conf");
        System.setProperty("java.security.auth.login.config", "/etc/kafka/2.3.4.0-3485/0/kafka_jaas.conf");
        System.setProperty("javax.security.auth.useSubjectCredsOnly", "false");
        System.setProperty("sun.security.krb5.debug", "true");

        try {
            long events = Long.parseLong("3");
            Random rnd = new Random();

            Properties props = new Properties();
            System.out.println("After broker list- " + args[0]);

            props.put("metadata.broker.list", args[0]);
            props.put("serializer.class", "kafka.serializer.StringEncoder");
            props.put("request.required.acks", "1");
            props.put("security.protocol", "PLAINTEXTSASL");

            //props.put("partitioner.class", "com.ct.test.kafka.SimplePartitioner");


            System.out.println("After config prop -1");

            ProducerConfig config = new ProducerConfig(props);

            System.out.println("After config prop -2 config" + config);

            Producer<String, String> producer = new Producer<String, String>(config);

            System.out.println("After config prop -3");

            for (long nEvents = 0L; nEvents < events; nEvents += 1L) {
                Date runtime = new Date();
                String ip = "192.168.2" + rnd.nextInt(255);
                String msg = runtime + " www.example.com, " + ip;
                KeyedMessage<String, String> data = new KeyedMessage<String, String>("test_march4", ip, msg);

                System.out.println("After config prop -1 data" + data);

                producer.send(data);
            }
            producer.close();

        } catch (Throwable th) {
            th.printStackTrace();

        }
    }
}

如果我在运行此应用程序之前执行 kinit，则效果很好，否则它将出现上述错误。 我无法在我的生产环境中执行此操作，如果我们的应用程序本身有任何方法可以执行此操作，请帮助我。 如果您需要更多详细信息，请告诉我。

Thanks:)

该错误位于 jaas 文件中的分号中，正如您在这段输出中看到的那样：

Line 6: expected [controlFlag]

该行不能有分号：

principal="ctadmin/[email protected]";

它只能存在于最后一行：
