Kafka Connect实施错误 [英] Kafka Connect implementation errors

问题描述

我在这里浏览了该教程: http://kafka.apache.org/documentation.html#introduction

I was running through the tutorial here: http://kafka.apache.org/documentation.html#introduction

当我进入第7步:使用Kafka Connect导入/导出数据"并尝试启动两个连接器时，出现以下错误:

When I get to "Step 7: Use Kafka Connect to import/export data" and attempt to start two connectors I am getting the following errors:

ERROR Failed to flush WorkerSourceTask{id=local-file-source-0}, timed out while waiting for producer to flush outstanding messages, 1 left

ERROR Failed to commit offsets for WorkerSourceTask

这是本教程的一部分:

接下来，我们将启动两个以独立模式运行的连接器，这意味着它们将在单个本地专用进程中运行.我们提供了三个配置文件作为参数.第一个始终是Kafka Connect流程的配置，其中包含通用配置，例如要连接的Kafka代理和数据的序列化格式.其余配置文件均指定要创建的连接器.这些文件包括唯一的连接器名称，要实例化的连接器类，以及连接器所需的任何其他配置. bin/connect-standalone.sh config/connect-standalone.properties config/connect-file-source.properties config/connect-file-sink.properties

我花了一些时间寻找解决方案，但是找不到有用的东西.任何帮助表示赞赏.

I have spent some time looking for a solution, but was unable to find anything useful. Any help is appreciated.

谢谢！

推荐答案

我收到此错误的原因是因为我使用config/server.properties创建的第一台服务器未运行.我假设是因为它是该主题的开头，所以无法刷新消息，也无法提交偏移量.

The reason I was getting this error was because the first server I created using the config/server.properties was not running. I am assuming that because it is the lead of the topic, the messages could not be flushed and the offsets could not be committed.

使用服务器属性(config/server.properties)启动kafka服务器后，此问题已解决.

Once I started the kafka server using the server propertes (config/server.properties) This issue was resolved.
