Question

在本地版本的Apache Flink中执行以下代码不会产生任何错误，但在远程群集上会产生以下错误！任何帮助表示赞赏！

 personRecords =  env.readCsvFile("dataPath/dataset.csv")
               .lineDelimiter("\n").fieldDelimiter(",")         
               .includeFields("11").types(Integer.class, String.class);

 partitionedData = personRecords.map(new cleanerMap());

错误显示如下：

Answer 1

如果找不到用户代码类，

TaskConfig.getStubWrapper()会抛出CorruptConfigurationException。

我会检查程序jar文件中是否包含cleanerMap类。

RegisterInputOutput（）远程群集上的错误，Apache Flink
