我是Spring云数据流的新手。

  1. 我在 kafka_2.11-1.1.0 中创建了一个主题 ./kafka-console-producer.sh --broker-list localhost:9092 --topic test

  2. 我在 Scdf 中注册了 redis-pubsub （ spring-cloud-dataflow-server-local-1.3.0.RELEASE.jar ）：

    3. sink.redis-pubsub=maven://org.springframework.cloud.stream.app:redis-sink-kafka-10:1.3.1.RELEASE

sink.redis-pubsub.metadata=maven://org.springframework.cloud.stream.app:redis-sink-kafka-10:jar:metadata:1.3.1.RELEASE
    1. 我在 Scdf :test>redis-pubsub --key=msgs --host=127.0.0.1 --port=6379中创建了以下流，但部署失败。

      2. 我想调试redis-pubsub源来理解这个问题，但我找不到它。你可以帮助我吗？

      这是流日志：

答案 0 :(得分：0)

当redis-sink应用程序无法连接到Redis群集时，会发生此错误。您似乎正在尝试连接到localhost。

你可以，

  1. 下载水槽
  2. 在本地启动Redis
  3. 通过以下方式将其作为独立应用运行：java -jar redis-sink-kafka-10:1.3.1.RELEASE.jar

    4. 如果一切设置正确，默认情况下，此应用程序应连接到localhost上的Redis实例。如果它在这种模式下工作，它也将在SCDF中。
