pyflink-1.12.0 stream api任务执行失败

[゛无邪]

Hi，您好！

我们参考Flink官网上提供的Python API中的DataStream API用户指南文档编写了一份python脚本，文档地址：https://ci.apache.org/projects/flink/flink-docs-release-1.12/zh/dev/python/datastream-api-users-guide/operators.html

flink运行方式是 on yarn，通过-py参数指定了脚本，能成功提交到yarn上，但是会遇到如下错误

Job has been submitted with JobID ee9e3a89eae69f457b81d1ebf4a45264
