> Key: STORM-2077

> Project: Apache Storm
> Issue Type: Bug
> Components: storm-kafka
> Affects Versions: 1.0.2
> Reporter: Tobias Maier
>
> KafkaSpout does not retry all failed tuples.
> We used following Configuration:
> Map<String, Object> props = new HashMap<>();
> props.put(KafkaSpoutConfig.Consumer.GROUP_ID, "c1");
> props.put(KafkaSpoutConfig.Consumer.KEY_DESERIALIZER,
> ByteArrayDeserializer.class.getName());
> props.put(KafkaSpoutConfig.Consumer.VALUE_DESERIALIZER,
> ByteArrayDeserializer.class.getName());
> props.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,
> broker.bootstrapServer());
> KafkaSpoutStreams kafkaSpoutStreams = new
> KafkaSpoutStreams.Builder(FIELDS_KAFKA_EVENT, new
> String[]{"test-topic"}).build();
> KafkaSpoutTuplesBuilder<byte[], byte[]> kafkaSpoutTuplesBuilder = new
> KafkaSpoutTuplesBuilder.Builder<>(new
> KeyValueKafkaSpoutTupleBuilder("test-topic")).build();
> KafkaSpoutRetryService retryService = new
> KafkaSpoutLoggedRetryExponentialBackoff(KafkaSpoutLoggedRetryExponentialBackoff.TimeInterval.milliSeconds(1),
> KafkaSpoutLoggedRetryExponentialBackoff.TimeInterval.milliSeconds(1), 3,
> KafkaSpoutLoggedRetryExponentialBackoff.TimeInterval.seconds(1));
> KafkaSpoutConfig<byte[], byte[]> config = new
> KafkaSpoutConfig.Builder<>(props, kafkaSpoutStreams, kafkaSpoutTuplesBuilder,
> retryService)
> .setFirstPollOffsetStrategy(UNCOMMITTED_LATEST)
> .setMaxUncommittedOffsets(30)
> .setOffsetCommitPeriodMs(10)
> .setMaxRetries(3)
> .build();
> kafkaSpout = new org.apache.storm.kafka.spout.KafkaSpout<>(config);
> The downstream bolt fails every tuple and we expect, that those tuple will
> all be replayed. But that's not the case for every tuple.
