将数据发送到Kerberos从scala Client启用Kafka群集-Java 学习之路

我正在写scala中的akka，Kafka Producer，我正在尝试从scala kafka客户端向kafka代理发送消息，问题是代理没有收到这些消息我通过从命令行启动kafka consumer来验证它 . Kafka的制作人和消费者在命令提示符下工作正常 . Kafka启用了Kerberos和SASL_PlainText安全性 .

请在下面找到我的conf文件，客户端代码和应用程序日志 . 我认为从代码连接到Kerberos时必定存在一些问题 .

Scala客户端：

package com.ABC.adds.producer

import akka.actor.ActorSystem
import akka.kafka.ProducerSettings
import akka.kafka.scaladsl.Producer
import akka.stream.ActorMaterializer
import akka.stream.scaladsl.Source
import com.ABC.adds.models.Models.GMMOfaq
import com.ABC.adds.producer.serializer.ModelSerializer
import com.thoughtworks.xstream.XStream
import com.thoughtworks.xstream.io.xml.DomDriver
import com.typesafe.config.ConfigFactory
import com.typesafe.scalalogging.LazyLogging
import org.apache.kafka.clients.CommonClientConfigs
import org.apache.kafka.clients.producer.{KafkaProducer, ProducerRecord, RecordMetadata}
import org.apache.kafka.common.serialization.ByteArraySerializer

import scala.concurrent.ExecutionContext.Implicits.global
import scala.util.{Failure, Success}

object faqProducer extends App with LazyLogging{

  val config = ConfigFactory.load()
  implicit val system = ActorSystem.create("adds-faq-producer", config)
  implicit val mat = ActorMaterializer()

  val producerSettings = ProducerSettings(system, new ByteArraySerializer, new ModelSerializer[PPOfaq](classOf[PPOfaq]))
  .withBootstrapServers("jbt12324.systems.pfk.ABC:3382")
     .withProperty(CommonClientConfigs.SECURITY_PROTOCOL_CONFIG, "SASL_PLAINTEXT")
      .withProperty("zookeeper.connect","jbt234234.systems.pfk.ABC:2341,jbt234.systems.pfk.ABC:234,jbt1234324.systems.pfk.ABC:2234")
      .withProperty(CommonClientConfigs.REQUEST_TIMEOUT_MS_CONFIG, "1")

  val xstream = new XStream(new DomDriver)
  val personString: String = scala.io.Source.fromInputStream(getClass().getClassLoader().getResourceAsStream("PPOfaq.xml")).mkString
  xstream.alias("faq", classOf[PPOfaq])
  val ppofaq: PPOfaq = xstream.fromXML(personString).asInstanceOf[PPOfaq]

  logger.info(s"Producer Configuration is : {} ", producerSettings.toString)
  logger.info(s"Sending message : {}", ppofaq)

  logger.info("KafkaProducer Send first fetching Partitions for topics")
  val  kafkaProducer  = producerSettings.createKafkaProducer()
  kafkaProducer.partitionsFor("asp.adds.ppo.pems")
  val done1 = kafkaProducer.send(new ProducerRecord[Array[Byte], PPOfaq]("asp.adds.ppo.pems", ppofaq))
  val recordMetaData : RecordMetadata = done1.get()

    logger.info("Topic is :  " + recordMetaData.topic() +" partition is : "+ recordMetaData.partition() +" offset is : "+ recordMetaData.offset() )

  logger.info("KafkaProdcuer Send first fetching Partitions for topics end")

  val done = Source.single(ppofaq)
    .map { elem =>
      new ProducerRecord[Array[Byte], PPOfaq]("asp.adds.ppo.pems", ppofaq)
    }
    .runWith(Producer.plainSink(producerSettings))

  done onComplete {
  case Success(s) => {
    logger.info(s"The producer has sent a message to the topic: asp.adds.ppo.pems!!")
  }
  case Failure(e) => {
    logger.error("Erorr occured while producing Topic", e)
    e.printStackTrace()
    e.fillInStackTrace()
    e.getCause
    e.getMessage
  }
}
}

这是我用于Kerberos身份验证的Kafka_Client Conf文件：

KafkaClient {
com.sun.security.auth.module.Krb5LoginModule required
doNotPrompt=true
useTicketCache=false
useKeyTab=true
serviceName="kafka"
principal="pqr@ASND.ADROOT.ABC"
keyTab="/home/pqr/.pqr.headless.keytab"
debug=true
client=true;
};
Client {
  com.sun.security.auth.module.Krb5LoginModule required
  doNotPrompt=true
  useKeyTab=true
  useTicketCache=false
  serviceName="zookeeper"
  principal="pqr@ASND.ADROOT.ABC"
  keyTab="/home/pqr/.pqr.headless.keytab"
  debug=true;
};

这是我在集群上运行jar时获得的应用程序日志：应用程序日志：

如果我做错了，请告诉我 . 谢谢，Mahendra Tonape

我们无法在我们的集群中消费来自消费者端的消息，但是我们能够在我们的本地机器上使用消息，因为我们使用Kafka 0.10编写了应用程序api，而我们的集群使用kafka版本0.9.如果您检查了这两者之间的差异在Kafka版本中，您会发现这两个版本API之间存在显着差异 .

另外，请启用Kerberos调试日志以检查用户是否已通过启用Kerberos的群集进行身份验证
