Apache kafka Kafka接收器：由于错误而停止时出错（org.apache.Kafka.connect.cli.ConnectStandalone:130）

我正在尝试将数据从一个流文件流到另一个文件。它在更早的时候工作，突然它提供了一个错误作为

由于错误而停止的错误（org.apache.kafka.connect.cli.ConnectStandalone:130）

。已重新启动zookeeper、kafka服务器、架构注册表、源和接收器连接器，但仍面临相同的问题，无法解决。任何建议都会有帮助

源连接器：

name=local-file-source
connector.class=FileStreamSource
tasks.max=1
file=/home/jimmacaulay/Desktop/ETL/Kafka/confluent-5.5.1/data/data/Jim_Source.csv
topic=Jim

name=local-file-sink
connector.class=FileStreamSink
tasks.max=1
file=/home/jimmacaulay/Desktop/ETL/Kafka/confluent-5.5.1/data/data/Jim_Sink.csv
topics=Jim

水槽连接器：

name=local-file-source
connector.class=FileStreamSource
tasks.max=1
file=/home/jimmacaulay/Desktop/ETL/Kafka/confluent-5.5.1/data/data/Jim_Source.csv
topic=Jim

name=local-file-sink
connector.class=FileStreamSink
tasks.max=1
file=/home/jimmacaulay/Desktop/ETL/Kafka/confluent-5.5.1/data/data/Jim_Sink.csv
topics=Jim

通过同时使用源和接收器属性启动

connectstandalone

，解决了此错误

sh connect-standalone ../config/connect-avro-standalone.properties ../config/connect-file-source_Topic_Jim.properties ../config/connect-file-sink_Topic_Jim.properties

早些时候，我单独启动了它，如下所示

sh connect-standalone ../config/connect-avro-standalone.properties ../config/connect-file-source_Topic_Jim.properties

sh connect-standalone ../config/connect-avro-standalone.properties ../config/connect-file-sink_Topic_Jim.properties

问题的起因,

当am单独启动时，

connectstandalone

首先使用端口号8083启动源属性。同样，当我启动接收器属性时，它尝试使用相同的端口号并失败

解决方案

在启动共享同一端口的独立连接时，源和接收器属性都应保持一致

---

或者在属性文件中定义不同的端口号并分别启动它

，或者使用connect distributed，它在一个端口上启动单个REST服务器，您可以在其中运行两个连接器
