私はKafkaコンシューマグループで複数のコンシューマインスタンスを試していましたが、常にkafka.common.NotLeaderForPartitionExceptionで失敗します。Kafka + SparkStreamingのコンシューマグループで複数のインスタンスを使用しているときNotLeaderForPartitionException
私のカフカクラスタは、3つのブローカーと、PartitionCount:2とReplicationFactor:3というトピックで構成されています。
SparkConsumer.java
public class SparkConsumer {
private static Function2<Integer, Integer, Integer> MyReducerFunc = (a, b) -> a + b;
public static void main(String[] args) throws Exception {
if (args.length < 2) {
System.err.println("Usage: SparkConsumer <brokers> <topics>\n" +
" <brokers> is a list of one or more Kafka brokers\n" +
" <topics> is a list of one or more kafka topics to consume from\n\n");
System.exit(1);
}
//StreamingExamples.setStreamingLogLevels();
String brokers = args[0];
String topics = args[1];
SparkConf sparkConf = new SparkConf().setMaster("local[5]").setAppName("SparkConsumer").set("spark.driver.host", "localhost");
JavaSparkContext sc = new JavaSparkContext(sparkConf);
// Create a StreamingContext with a 2 second batch size
JavaStreamingContext jssc = new JavaStreamingContext(sc, Durations.seconds(2));
Set<String> topicsSet = new HashSet<>(Arrays.asList(topics.split(",")));
Map<String, String> kafkaParams = new HashMap<>();
kafkaParams.put("metadata.broker.list", brokers);
//kafkaParams.put("auto.offset.reset", "smallest");
kafkaParams.put("group.id", "SparkConsumerGrp");
kafkaParams.put("zookeeper.connect", "localhost:2181");

JavaPairDStream<String, String> messages2 =
messages.window(Durations.seconds(30), Durations.seconds(30));
messages2.foreachRDD(rdd -> {
long numHits = rdd.count();
if(numHits == 0)
System.out.println("No new data fetched in last 30 sec");
//Do Processing
else{
System.out.println("\n\n----------------------------------Data fetched in the last 30 seconds: " + rdd.partitions().size()

//Convert to java log object
JavaRDD<ApacheAccessLog> logs = rdd.map(x-> x._2)
.map(ApacheAccessLog::parseFromLogLine)
.cache();
//Find the bot ip addresses
JavaRDD<String> iprdd = logs.mapToPair(ip-> new Tuple2<>(ip.getIpAddress(),1))
.reduceByKey(MyReducerFunc)
.filter(botip-> botip._2 > 50)
.keys();
//If we find something, we store it in results dir on hdfs

//sc.hadoopConfiguration().set("mapreduce.output.basename", timeStamp);
iprdd.coalesce(1).saveAsTextFile("hdfs://quickstart.cloudera:8020/results/"+timeStamp);
JobConf jobConf=new JobConf();

}
});
jssc.start();
jssc.awaitTermination();
}
}
documentationからの私の理解では、私たちが既存のグループにそのインスタンスを追加するために、同じグループIDを持つ別のコンシューマ・プロセスを開始することができますということでした。したがって、私は2つの別々の端末でこのコードを実行します。
最初のインスタンスで：しかし、これは私が常に取得エラーです番目のインスタンスで
