[英]how to specify kafka brokers with KafkaIO in Apache Beam
I'm trying to setup a KafkaIO pipeline but i can't figure out how to specify brokers.我正在尝试设置 KafkaIO 管道,但我不知道如何指定代理。 Speficying brokername and port doesn't seem to do it.指定经纪人名称和端口似乎并没有这样做。 At no point am I specifying where my kafka cluster is:我从来没有指定我的 kafka 集群在哪里:
pipeline
.apply(KafkaIO.<Long, String>read()
.withBootstrapServers("broker.id__1:9092")
.withTopic("pageviews")
which gives me the error:这给了我错误:
Exception in thread "main" org.apache.beam.sdk.Pipeline$PipelineExecutionException: org.apache.kafka.common.KafkaException: Failed to construct kafka consumer
at org.apache.beam.sdk.Pipeline.run(Pipeline.java:323)
...
Caused by: org.apache.kafka.common.config.ConfigException: No resolvable bootstrap urls given in bootstrap.servers
My Kafka cluster is running locally and the broker id is correct.我的 Kafka 集群在本地运行,并且代理 ID 正确。
What am i missing?我错过了什么? What's the right way of specifying brokers?指定经纪人的正确方法是什么?
Turns out it's simply原来这很简单
withBootstrapServers("localhost:9092")
