回复: Re: 提交flink作业抛 java.lang.LinkageError

[WuKong <wu...@foxmail.com>]

Hi :
    看报错日志，还是类加载问题 提示的报错信息 是说已经由不同类加载器已经加装了改依赖。如果生产环境上已经由了相关依赖包，建议将依赖设置为provided

Caused by: java.lang.LinkageError: loader constraint violation: loader
>> (instance of org/apache/flink/util/ChildFirstClassLoader) previously
>> initiated loading for a different type with name
>> "org/apache/kafka/clients/consumer/ConsumerRecord"
