apache-storm - KafkaSpout 中的异常

问题描述

我正在关注异常风暴拓扑。

我正在使用已弃用的storm-kafka 库。如果这是上述异常的原因，那么让我知道如何使用storm-kafka-client 库创建kafka spout 并将自定义方案传递给它。

谢谢。

解决方案

您能否尝试将org.apache.kafka:kafka-clients工件也放入您的依赖项中，与 相同的版本kafka_2.11？

关于如何使用storm-kafka-client，在 https://storm.apache.org/releases/2.0.0-SNAPSHOT/storm-kafka-client.html 的 Storm 页面上有文档，在https://github有示例.com/apache/storm/blob/master/examples/storm-kafka-client-examples/src/main/java/org/apache/storm/kafka/spout/KafkaSpoutTopologyMainNamedTopics.java

具体来说，您想要的是RecordTranslator.

ByTopicRecordTranslator<String, String> trans = new ByTopicRecordTranslator<>(
            (r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
            new Fields("topic", "partition", "offset", "key", "value"), TOPIC_0_1_STREAM);
        trans.forTopic(TOPIC_2,
            (r) -> new Values(r.topic(), r.partition(), r.offset(), r.key(), r.value()),
            new Fields("topic", "partition", "offset", "key", "value"), TOPIC_2_STREAM);
        return KafkaSpoutConfig.builder(bootstrapServers, new String[]{TOPIC_0, TOPIC_1, TOPIC_2})
            .setProp(ConsumerConfig.GROUP_ID_CONFIG, "kafkaSpoutTestGroup")
            .setRetry(getRetryService())
            .setRecordTranslator(trans)
            .setOffsetCommitPeriodMs(10_000)
            .setFirstPollOffsetStrategy(EARLIEST)
            .setMaxUncommittedOffsets(250)
.build();

例如，这会从列出的字段中的每条记录中输出主题、分区、偏移量、键和值，并将从 TOPIC_2 发出元组到与其他订阅主题不同的流。如果您不需要针对不同主题使用不同的方案，则可以SimpleRecordTranslator改用。
