Hi all
kafka version : kafka_2.11-0.11.0.2
A topic-partition "adn-tracking,15" in kafka who's earliest offset is1255644602
andlatest offset is1271253441.
While starting a spark streaming to process the data from the topic , we got a
exception with "Got wrong record XXXX even after seeking to offset 1266921577”.
[ (earliest offset) 1255644602 1266921577 1271253441 ( latest offset ) ]
Iimplemented a simple project to use consumer to seek offset 1266921577. But it
return the offset1266921578. Then while seek to1266921576, it return
the1266921576exactly。
Why ? How to fix that ?
There is the code:
public class consumerDemo {
public static void main(String[] argv){
Properties props = new Properties();
props.put("bootstrap.servers", "172.31.29.31:9091");
props.put("group.id", "consumer-tutorial-demo");
props.put("key.deserializer", StringDeserializer.class.getName());
props.put("value.deserializer", StringDeserializer.class.getName());
KafkaConsumerString, String consumer = new KafkaConsumerString, String(props);
TopicPartition tp = new TopicPartition("adn-tracking-click", 15);
CollectionTopicPartition collection = new ArrayListTopicPartition();
collection.add(tp); consumer.assign(collection);
consumer.seek(tp, 1266921576); ConsumerRecordsString, String consumerRecords =
consumer.poll(10000);
ListConsumerRecordString, String listR = consumerRecords.records(tp);
IteratorConsumerRecordString, String iter = listR.iterator();
ConsumerRecordString, String record = iter.next();
System.out.println(" the next record " + record.offset() + " recode topic " +
record.topic());
}
}
