---------------------------
Summary: Failed to send data to Kafka
Key: FLINK-18575
URL: https://issues.apache.org/jira/browse/FLINK-18575
Project: Flink
Issue Type: Bug
Components: API / DataStream
Affects Versions: 1.10.0
Reporter: mzz
Flink version: 1.10.0
Kafka version: 2.2
*code:*
{code:java}
private def producerKafka(aggs_result: DataStream[String], topic: String,
parallelism: Int) = {
val kafkaPro = new Properties()
kafkaPro.setProperty("bootstrap.servers", SINK_BROKERS)
kafkaPro.setProperty("zookeeper.connect", SINK_ZK)
kafkaPro.setProperty("request.timeout.ms", "10000")
kafkaPro.setProperty("compression.type", "snappy")
kafkaPro.setProperty("transaction.timeout.ms", 1000 * 60 * 5 + "")
// 设置了retries参数，可以在Kafka的Partition发生leader切换时，Flink不重启，而是做5次尝试：
kafkaPro.setProperty(ProducerConfig.RETRIES_CONFIG, "5")
val kafka = new FlinkKafkaProducer[String](topic, new
ResultDtSerialization(topic), kafkaPro,
FlinkKafkaProducer.Semantic.AT_LEAST_ONCE)
aggs_result.addSink(kafka).setParallelism(parallelism)
}
