Apache kafka 如何在分布式模式下运行Kafka connect replicator？

我想使用confluent的replicator将数据从一个系统复制到另一个系统。我使用两个Ubuntu18.04系统，其中一个作为源，另一个作为目标

我尝试在分布式模式下运行kafka connect replicator，更改了以下配置：

在confluent/etc/kafka/server.properties中，我做了以下更改

在confluent/etc/kafka connect replicator/replicator.connect.distributed.properties中，我做了以下更改

在confluent/etc/kafka connect replicator/quickstart-replicator.properties中，我更改了以下配置

来源

name=replicator-source
connector.class=io.confluent.connect.replicator.ReplicatorSourceConnector
# source cluster connection info
src.kafka.bootstrap.servers=source.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the source
src.zookeeper.connect=localhost:2181

# destination cluster connection info
dest.kafka.bootstrap.servers=destination.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the destination
dest.zookeeper.connect=destination.ip:2181
# configure topics to replicate
topic.whitelist= test-topic
topic.rename.format=${topic}.replica

目的地

name=replicator-source
connector.class=io.confluent.connect.replicator.ReplicatorSourceConnector
# source cluster connection info
src.kafka.bootstrap.servers=source.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the source
src.zookeeper.connect=source.ip:2181

# destination cluster connection info
dest.kafka.bootstrap.servers=destination.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the destination
dest.zookeeper.connect=destination.ip:2181
# configure topics to replicate
topic.whitelist= test-topic
topic.rename.format=${topic}.replica

然后我在源系统中创建了topic，并使用下面的命令启动了连接器

PATH\u TO\u CONFLUENT>sudo./bin/connect distributed./etc/kafka connect replicator/replicator-connect-distributed.properties./etc/kafka connect replicator/quickstart replicator.properties

---

在此之后，我从源系统生成了主题中的数据，并尝试使用主题名{topic}.replica在目标系统中使用，但没有可用于使用的主题。

不清楚您有哪些错误，但有一些注意事项

connectdistributed

只获取一个属性文件，而不是两个。您可以将属性作为JSON以HTTP方式发布到Connect集群，而不是在集群启动期间加载属性文件。快速启动文件用于

connectstandalone

JSON看起来像

{"name": "your-replicator-name", "config": {
  "src.kafka.bootstrap.servers": "...",
  ...
}

/etc/kafka/connect distributed.properties

应该是以分布式模式运行任何connect或Replicator群集的起点，尽管在

Replicator connect distributed.properties中可能有类似的配置

bootstrap.server

应该只指向一个集群。源和目标将在

src.kafka.bootstrap.servers

和

dest.kafka.bootstrap.servers

---

是的，我知道了。我终于能够将数据从源系统复制到目标系统。我在源系统中创建主题，并在目标系统中运行confluent replicator。

name=replicator-source
connector.class=io.confluent.connect.replicator.ReplicatorSourceConnector
# source cluster connection info
src.kafka.bootstrap.servers=source.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the source
src.zookeeper.connect=source.ip:2181

# destination cluster connection info
dest.kafka.bootstrap.servers=destination.ip:9092
# Set to use direct connection to Zookeeper by Replicator on the destination
dest.zookeeper.connect=destination.ip:2181
# configure topics to replicate
topic.whitelist= test-topic
topic.rename.format=${topic}.replica

{"name": "your-replicator-name", "config": {
  "src.kafka.bootstrap.servers": "...",
  ...
}
