配置

查看CDH中配置是否和下面一樣，不一樣則修改

Java Producer 代碼

這里只列出配置的代碼，其他的與普通producer相同

import org.apache.kafka.clients.producer.Producer; import org.apache.kafka.clients.producer.ProducerRecord; import org.apache.kafka.clients.producer.RecordMetadata;import java.io.IOException; import java.util.ArrayList; import java.util.Calendar; import java.util.Date; import java.util.List; import java.util.Properties; import java.util.concurrent.ArrayBlockingQueue; import java.util.concurrent.BlockingQueue; import java.util.concurrent.ExecutionException; import java.util.concurrent.Future;public class KafkaProducer {private static BlockingQueue<Future<RecordMetadata>> queue = new ArrayBlockingQueue<Future<RecordMetadata>>(8192*2);private static long lastCommitTime = 0;private static boolean flag = true;Producer<String, String> producer = null;public KafkaProducer() {System.setProperty("java.security.auth.login.config", "C:\\Users\\Administrator\\eclipse-workspace\\kafka\\src\\main\\resources\\kafka_client_jaas.conf");System.setProperty("java.security.krb5.conf", "C:\\Users\\Administrator\\eclipse-workspace\\kafka\\src\\main\\resources\\krb5.conf");//這里也可以使用提交方式指定配置文件 -Djava.security.krb5.conf=/krb5.conf -Djava.security.auth.login.config=/kafka_server_jaas.confProperties props = new Properties();props.put("bootstrap.servers", KafkaParameter.KAFKA_HOST_IP);props.put("acks", "all");props.put("retries", 0);props.put("batch.size", 16384);props.put("linger.ms", 1);props.put("buffer.memory", 33554432);props.put("max.request.size", 8000000);props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");props.put("security.protocol", "SASL_PLAINTEXT");this.producer = new org.apache.kafka.clients.producer.KafkaProducer<>(props);}}

kafka.keytab

? ? ? ? kerberos生成的keytab文件

生成文件方式：

kadmin.local -q "xst -norandkey -k kafka.keytab kafka@JAST.COM"

具體可參考：

https://datamining.blog.csdn.net/article/details/98625330

Java Consumer 代碼?

與Producer基本一致，文件說明參考Producer代碼

import java.util.Arrays; import java.util.Date; import java.util.Properties;import org.apache.kafka.clients.consumer.ConsumerRecord; import org.apache.kafka.clients.consumer.ConsumerRecords;public class KafkaConsumer {private static KafkaConsumer kafkaSink = null;org.apache.kafka.clients.consumer.KafkaConsumer consumer;private static int number;public KafkaConsumer(String topic,int count) {System.setProperty("java.security.auth.login.config", "C:\\Users\\Administrator\\eclipse-workspace\\kafka\\src\\main\\resources\\kafka_client_jaas.conf");System.setProperty("java.security.krb5.conf", "C:\\Users\\Administrator\\eclipse-workspace\\kafka\\src\\main\\resources\\krb5.conf");//這里也可以使用提交方式指定配置文件 -Djava.security.krb5.conf=/krb5.conf -Djava.security.auth.login.config=/kafka_server_jaas.confProperties props = new Properties();props.put("bootstrap.servers", KafkaParameter.KAFKA_HOST_IP);props.put("group.id", "y" );props.put("zookeeper.session.timeout.ms", "600000");props.put("zookeeper.sync.time.ms", "200000");props.put("auto.commit.interval.ms", "100000");props.put(org.apache.kafka.clients.consumer.ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, "earliest");props.put("key.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");props.put("value.deserializer", "org.apache.kafka.common.serialization.StringDeserializer");props.put(org.apache.kafka.clients.consumer.ConsumerConfig.MAX_POLL_RECORDS_CONFIG, count+"");//設置最大消費數props.put("security.protocol", "SASL_PLAINTEXT");consumer = new org.apache.kafka.clients.consumer.KafkaConsumer(props);consumer.subscribe(Arrays.asList(topic)); //"collectionInfo"}}

Linux 控制臺消費

生成kafka用戶keytab文件

kadmin.local -q "xst -norandkey -k kafka.keytab kafka@JAST.COM"

生成kafka_client_jaas.conf文件,位置隨意,內容如下

# cat config/kafka_jaas.conf KafkaClient {com.sun.security.auth.module.Krb5LoginModule requireduseKeyTab=truekeyTab="/root/jast/kafka.keytab"storeKey=trueuseTicketCache=falseprincipal="kafka@JAST.COM"serviceName=kafka;};Client {com.sun.security.auth.module.Krb5LoginModule requireduseKeyTab=truekeyTab="/root/jast/kafka.keytab"storeKey=trueuseTicketCache=falseprincipal="kafka@JAST.COM"serviceName=kafka; };

添加環境變量引用jaas文件

export KAFKA_OPTS="-Djava.security.auth.login.config=/opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/config/kafka_client_jaas.conf"

創建consumer.properties文件，內容如下

security.protocol=SASL_PLAINTEXT sasl.mechanism=GSSAPI sasl.kerberos.service.name=kafka group.id=test11

此時就可以消費了

/opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/bin/kafka-console-consumer.sh --bootstrap-server 192.168.0.200:9092 --topic test --from-beginning --consumer.config /opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/config/consumer.properties

成功消費數據

Linux 控制臺發送數據數據

創建producer.properties文件，內容如下

# cat producer.properties security.protocol=SASL_PLAINTEXT sasl.mechanism=GSSAPI sasl.kerberos.service.name=kafka

發送數據

/opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/bin/kafka-console-producer.sh --broker-list 192.168.0.200:9092 --topic test --producer.config /opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/config/producer.properties

Producer

查看Consumer?消費成功

Linux 控制臺創建、刪除Topic

在linux 系統配置上面設置的jaas環境變量后即可

export KAFKA_OPTS="-Djava.security.auth.login.config=/opt/cloudera/parcels/CDH-6.0.1-1.cdh6.0.1.p0.590678/lib/kafka/config/kafka_jaas.conf"
