Question

我使用storm 1.0.1和Kafka 0.10.0.0使用storm-kafka-client 1.0.3。

请找到我在下面的代码配置。

kafkaConsumerProps.put(KafkaSpoutConfig.Consumer.KEY_DESERIALIZER, "org.apache.kafka.common.serialization.ByteArrayDeserializer");
            kafkaConsumerProps.put(KafkaSpoutConfig.Consumer.VALUE_DESERIALIZER, "org.apache.kafka.common.serialization.ByteArrayDeserializer");


            KafkaSpoutStreams kafkaSpoutStreams = new KafkaSpoutStreamsNamedTopics.Builder(new Fields(fieldNames), topics)
                    .build();

            KafkaSpoutRetryService retryService = new KafkaSpoutRetryExponentialBackoff(TimeInterval.microSeconds(500),
                                TimeInterval.milliSeconds(2), Integer.MAX_VALUE, TimeInterval.seconds(10));


            KafkaSpoutTuplesBuilder tuplesBuilder = new KafkaSpoutTuplesBuilderNamedTopics.Builder(new TestTupleBuilder(topics))
                        .build();

            KafkaSpoutConfig kafkaSpoutConfig = new KafkaSpoutConfig.Builder<String, String>(kafkaConsumerProps, kafkaSpoutStreams, tuplesBuilder, retryService)
                                                                .setOffsetCommitPeriodMs(10_000)
                                                                .setFirstPollOffsetStrategy(LATEST)
                                                                .setMaxRetries(5)
                                                                .setMaxUncommittedOffsets(250)
                                                                .build();

当我失败时，它没有被重播。 Spout抛出错误。请让我知道为什么它会抛出nullpointer异常。

请在下面找到完整的喷嘴配置 {key.deserializer = org.apache.kafka.common.serialization.ByteArrayDeserializer,value.deserializer = org.apache.kafka.common.serialization.ByteArrayDeserializer,group.id = test-group，ssl.keystore.location = C：/ test.jks，bootstrap.servers = localhost：1000，auto.commit.interval.ms = 1000，security.protocol = SSL，enable.auto.commit = true，ssl.truststore.location = C：/test1.jks,ssl .keystore.password = pass123，ssl.key.password = pass123，ssl.truststore.password = pass123，session.timeout.ms = 30000，auto.offset.reset = latest}

Answer 1

Storm 1.0.1由测试版质量的storm-kafka-client组成。我们已经解决了一些问题，Storm 1.1版本中提供了更稳定的版本，可用于Kafka 0.10以后。在您的拓扑中，您可以使用适当的版本依赖storm-kafka-client版本1.1和kafka-clients依赖项。您无需升级风暴群集本身。

Answer 2

我有enable.auto.commit = true使值为false解决了我的问题。
