我已经启动了 Hazelcast-Jet(jet-start.sh) 的 3 个实例。可以看到集群形成为 3 个节点。
在其中一个集群节点中，我尝试pipeline使用JetClientto Source from KafkatoIMap和 source from IMapto运行很少的Kafka。这是代码：
public static void main(String[] args) throws Exception {
new SourceKafkaToIMapForEnrichments().run();
}
private void run() throws Exception {
JetConfig cfg = new JetConfig();
cfg.setInstanceConfig(
new InstanceConfig().setCooperativeThreadCount(Math.max(1, getRuntime().availableProcessors() / 1)));
try {
// jetInstance = Jet.newJetInstance(cfg);
// Jet.newJetInstance(cfg);
UsernamePasswordCredentials cred = new UsernamePasswordCredentials("jet", "jet-app");
jetInstance = Jet.newJetClient(new ClientConfig().setCredentials(cred));
JobConfig jobConfig = new JobConfig();
jobConfig.addClass(SourceKafkaToIMapForEnrichments.class);
initiateMaps(); // initialize maps
Pipeline sourceFromClient = buildPipelineForClientDataa();
Pipeline sourceFromIP2Location = buildPipelineForIp2Loc();
Pipeline enrichSinkToKafka = buildPipelineForEnrichData();
long start = System.nanoTime();
Job job1 = jetInstance.newJob(sourceFromClient, jobConfig);
Job job2 = jetInstance.newJob(sourceFromIP2Location, jobConfig);
Job job3 = jetInstance.newJob(enrichSinkToKafka, jobConfig);
}
}
private static Pipeline buildPipelineForClientDataa() {
Pipeline p = Pipeline.create();
p.drawFrom(KafkaSources.kafka(
props(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS,
ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getCanonicalName(),
ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getCanonicalName(),
ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, AUTO_OFFSET_RESET),
record -> com.hazelcast.jet.Util.entry( com.hazelcast.jet.datamodel.Tuple2.tuple2(record.partition(), record.offset()),
record.value()), SINK_CLINET_DATA)).withoutTimestamps().drainTo(Sinks.map(SINK_CLINET_DATA));
return p;
}
private static Pipeline buildPipelineForIp2Loc() {
Pipeline p = Pipeline.create();
p.drawFrom(KafkaSources.kafka(
props(ConsumerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS,
ConsumerConfig.KEY_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getCanonicalName(),
ConsumerConfig.VALUE_DESERIALIZER_CLASS_CONFIG, StringDeserializer.class.getCanonicalName(),
ConsumerConfig.AUTO_OFFSET_RESET_CONFIG, AUTO_OFFSET_RESET),
record -> com.hazelcast.jet.Util.entry(
com.hazelcast.jet.datamodel.Tuple2.tuple2(record.partition(), record.offset()),
record.value()),
SINK_IP2LOCATION))
.withoutTimestamps()
.drainTo(Sinks.map(SINK_IP2LOCATION));
return p;
}
private static Pipeline buildPipelineForEnrichData() {
Pipeline p = Pipeline.create();
p.drawFrom(Sources.map(SINK_CLINET_DATA_ENRICHED))
.drainTo(KafkaSinks.kafka(
props(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, BOOTSTRAP_SERVERS,
ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getCanonicalName(),
ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getCanonicalName()),
SINK_CLINET_DATA_ENRICHED));
return p;
}
private static Properties props(String... kvs) {
final Properties props = new Properties();
for (int i = 0; i < kvs.length;) {
props.setProperty(kvs[i++], kvs[i++]);
}
return props;
}
public static IMap<Tuple2<Integer, Long>, ApacheCommons> clientMapObject = null;
public static IMap<Tuple2<Integer, Long>, IP2LocationPojo> ip2LocIMapObjectLevel = null;
public static IMap<String, ApacheCommons> clientMapEnriched = null;
@SuppressWarnings("deprecation")
private void initiateMaps() {
// client data -> topic to Imap
jetInstance.getMap(SINK_CLINET_DATA).addEntryListener(new KafkaStreamIMapListener(), true);
// ip2location data -> topic to Imap
jetInstance.getMap(SINK_IP2LOCATION).addEntryListener(new KafkaIp2LocationListener(), true);
// client data -> json string to Java object
clientMapObject = jetInstance.getMap(SINK_CLINET_DATA_OBJECT);
clientMapObject.addEntryListener(new KafkaStreamObjectIMapListener(), true);
// ip2location data -> string to JAva object
ip2LocIMapObjectLevel = jetInstance.getMap(SINK_IP2LOCATION_OBJECT);
// client data -> enrich data by adding geoloc information
clientMapEnriched = jetInstance.getMap(SINK_CLINET_DATA_ENRICHED);
// clientMapEnriched.addEntryListener(new KafkaStreamObjectIMapListener(), true);
}
虽然代码中没有，但我正在使用org/apache/kafka/clients/consumer/ConsumerRecord，在运行这个 jar 时，我收到了这个错误：

虽然我添加了 的依赖项kafka-clients，但仍然遇到此错误。这是 pom.xml：
<dependencies>
<!-- https://mvnrepository.com/artifact/com.hazelcast.jet/hazelcast-jet-kafka -->
<dependency>
<groupId>com.hazelcast.jet</groupId>
<artifactId>hazelcast-jet-kafka</artifactId>
<version>3.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.hazelcast.jet/hazelcast-jet -->
<dependency>
<groupId>com.hazelcast.jet</groupId>

<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>2.2.0</version>
</dependency>
</dependencies>
也添加kafka-clients.jar到/Hazelcast-jet-3.0/lib文件夹中。想知道我是否应该开始Hazelcast IMDG？
有人请帮助和纠正。谢谢。
