我正在探索合流Kafka和以下从合流快速入门指南。我要走了 java.lang.ClassNotFoundException: io.confluent.monitoring.clients.interceptor.MonitoringProducerInterceptor
每当我尝试使用以下命令为Kafka主题创建一些示例数据时:
bin/ksql-datagen quickstart=pageviews format=delimited topic=pageviews maxInterval=100 \ propertiesFile=etc/ksql/datagen.properties
这是堆栈跟踪
Outputting 1000000 to pageviews

我已经遵循了快速入门指南中给出的每一步,我做错了什么?
我甚至重申了合流,但仍然得到相同的错误,而不是什么在这个谷歌集团的答案中提到的

$confluent\u home/share/java/monitoring interceptors/monitoring interceptors-*.jar

我在/etc/ksql/datagen.properties中遇到了同样的问题,发现它只适用于confluent enterprise:
它在删除属性文件后工作:
