Flink1.20.1集成Paimon遇到的问题

flinkcdc mysql 到paimon

1：Caused by: java.lang.ClassNotFoundException: org.apache.kafka.connect.data.Schema

可以参考这个文章明确指出了flink-connector-mysql-cdc-3.4.0.jar存在这个包，但是flink-sql-connector-mysql-cdc-3.4.0.jar中没有这个包可以在maven仓库中看到
在这里插入图片描述

缺少 kafka的 connect-api-3.3.2.jar

2:Caused by: java.io.InvalidClassException: org.apache.flink.cdc.connectors.shaded.com.fasterxml.jackson.databind.cfg.MapperConfig; incompatible types for field _mapperFeatures

不能同时存在
flink-connector-mysql-cdc-3.4.0.jar
flink-sql-connector-mysql-cdc-3.4.0.jar

3:cannot assign instance of java.lang.invoke.SerializedLambda to field org.apache.flink.streaming.api.operators.AbstractUdfStreamOperator.userFunction of type org.apache.flink.api.common.functions.Function in instance of org.apache.flink.streaming.api.operators.StreamFlatMap

dinky standalone 提mysqlCDC整库同步到paimon
将dinky-app的依赖丢进flink lib中就可以了
