Поток данных между SASL_SSL защищенным кластером Kafka и кластером Hadoop Kerberised с использованием spark_streaming

/ 25 января 2019

Я подключаюсь к Kafka Brokers, защищенным с помощью SSL, и опрашиваю каждые 60 секунд. затем, используя опрошенные данные, я создаю искровой фрейм данных, но когда я записываю его в таблицы кустов, он выдает ОШИБКУ, и приложение завершается.

Потребитель работает в кластере Kerberised Hadoop.

код потребителя использует следующий

jaas.config: 

KafkaClient{
      org.apache.kafka.common.security.plain.PlainLoginModule required  
      username = "***" 
      password  = "***";
      };

build.sbt 

scalaVersion := "2.11.8"
val sparkVersion = "2.2.0"

libraryDependencies ++= Seq(
  "org.apache.spark" % "spark-core_2.11" % sparkVersion % "provided",
  "org.apache.spark" % "spark-sql_2.11" % sparkVersion % "provided",
  "org.apache.spark" % "spark-hive_2.11" % sparkVersion % "provided",
  "org.apache.spark" % "spark-streaming_2.11" % sparkVersion % "provided",
  "org.apache.spark" %% "spark-streaming-kafka-0-10" % sparkVersion,
  "org.apache.kafka" % "kafka-clients" % "0.11.0.2"
)

KafkaConsumer.scala 

val spark = SparkSession.builder()
      .appName("SparkStreaming")
      .config("spark.driver.allowMultipleContexts", "true")
      .getOrCreate()

val sc = spark.sparkContext

val kafkaParams = Map[String, Object](
      "bootstrap.servers" -> "kafka-dev.xyz.com:9190",
      "key.deserializer" -> classOf[StringDeserializer],
      "value.deserializer" -> classOf[StringDeserializer],
      "group.id" -> "Scala_DEV",
      "auto.offset.reset" -> "latest",
      "enable.auto.commit" -> (false: java.lang.Boolean),

      "ssl.keystore.location" -> "ca-cert-sha1n2.jks",
      "ssl.keystore.password" -> "***",
      "ssl.truststore.password" -> "***",
      "ssl.truststore.location" -> "ca-cert-sha1n2.jks",
      "ssl.truststore.type" -> "JKS",
      "ssl.keystore.type" -> "JKS",
      "sasl.mechanism" -> "PLAIN",
      "ssl.key.password" -> ""
    )

val ssc = new StreamingContext(sc, Seconds(60))

val preferredHosts = LocationStrategies.PreferConsistent

val offsets = Map(new TopicPartition("Test_Topic", 0) -> 5L)

val dstream = KafkaUtils.createDirectStream[String, String](
      ssc,
      preferredHosts,
      ConsumerStrategies.Subscribe[String, String](topics, kafkaParams, offsets))

dstream.foreachRDD { rdd => {
        val json_df = spark.read.json(rdd.map(_.value()))
        json_df.show()
        json_df.write.insertInto("stage_load.Test_Table")
    }
}

ssc.start

ssc.awaitTermination()

когда я запускаю приведенный выше код с помощью приведенной ниже команды spark2-submit: 

SPARK_KAFKA_VERSION=0.10 spark2-submit --master yarn --deploy-mode client --files jaas.conf,ca-cert-sha1n2.jks \ 
--driver-java-options "-Djava.security.auth.login.config=jaas.conf" \

--conf "spark.driver.extraJavaOptions=-Djava.security.auth.login.config=jaas.conf" \ 
KafkaConsumer-assembly-0.1.jar

Я вижу, как заполняется информационный фрейм, но когда он записывается в таблицы кустов, он выдает следующие журналы искры:
