前言
在这之前做SparkStreaming连接Kafka，我会这么写：
val sparkConf = new SparkConf().setAppName("Spark2Kafka")
val ssc = new StreamingContext(sparkConf, Seconds(5))
ssc.checkpoint("/xxx/xxx")
val kafkaParameters = Map[String, String]("metadata.broker.list" -> "Master:9092,Worker1:9092,Worker2:9092")
val topics = Set[String]("TOPIC_NAME")
val streaming = KafkaUtils.createDirectStream[String, String, StringDecoder, StringDecoder](ssc, kafkaParameters, topics)
不过最近我们需要读取数据中心的Kafka数据，人家直接给了我三个值：username、password、group_id，我刚开始还一头雾水：这是干啥啊？于是还按照之前的写法，发现：
INFO consumer.SimpleConsumer: Reconnect due to error:
java.nio.channels.ClosedChannelException
原因分析
数据中心给的这三个字段看样子是用来做登录验证的，于是参考了官网链接
原来登录别人的Kafka需要SSL协议，这个时候就需要用户名和密码了，并且：0.8版本是不支持的，因此要依赖1.0版本的
详细流程
- 依赖
groupId = org.apache.spark
artifactId = spark-streaming-kafka-0-10_2.12
version = 2.4.3
- 写spark代码参考官网
package cn.unisk
import org.apache.kafka.common.serialization.StringDeserializer
import org.apache.spark.SparkConf
import org.apache.spark.streaming.{Seconds, StreamingContext}
import org.apache.spark.streaming.kafka010._
import org.apache.spark.streaming.kafka010.LocationStrategies.PreferConsistent
import org.apache.spark.streaming.kafka010.ConsumerStrategies.Subscribe
object Spark2Kafka {
def main(args: Array[String]) {
val kafkaParams = Map[String, Object](
"bootstrap.servers" -> "10.161.xx.xxx:9092,10.161.xx.xxx:9092,10.161.xx.xxx:9092",
"key.deserializer" -> classOf[StringDeserializer],
"security.protocol" -> "SASL_PLAINTEXT",
"sasl.mechanism" -> "PLAIN",
"value.deserializer" -> classOf[StringDeserializer],
"auto.offset.reset" -> "latest",
"group.id" -> "EC_group",
"enable.auto.commit" -> (false: java.lang.Boolean)
)
val sparkConf = new SparkConf().setAppName("Spark2_KafkaSASL")
val streamingContext = new StreamingContext(sparkConf, Seconds(5))
val topics = Array("CB_JF_ACT1")
val stream = KafkaUtils.createDirectStream[String, String](
streamingContext,
PreferConsistent,
Subscribe[String, String](topics, kafkaParams)
)
// Get the lines, split them into words, count the words and print
stream.map(record => (record.key, record.value))
stream.print()
// Start the computation
streamingContext.start()
streamingContext.awaitTermination()
}
}
- 在提交spark代码的服务器上创建jass.conf文件，内容如下
KafkaClient {
org.apache.kafka.common.security.plain.PlainLoginModule required
username="xxxx"
password="xxxx";
};
- 提交spark代码（和平时有点区别哦）
注意–先要做这样一个操作：
export SPARK_KAFKA_VERSION=0.10
如果不做，直接报错：
Caused by: java.lang.ClassNotFoundException: org.apache.spark.streaming.kafka010.KafkaUtils$
spark2-submit \
--master yarn \
--deploy-mode client \
--files /home/analysis/jass.conf \
--driver-java-options "-Djava.security.auth.login.config=./jass.conf" \
--conf "spark.executor.extraJavaOptions=-Djava.security.auth.login.config=./jass.conf" \
--class cn.unisk.Spark2Kafka \
/home/analysis/ss.jar
这里比平时多加了三个配置
--files /home/analysis/jass.conf \
--driver-java-options "-Djava.security.auth.login.config=./jass.conf" \
--conf "spark.executor.extraJavaOptions=-Djava.security.auth.login.config=./jass.conf" \
