apache-flink - Flink 1.14 - 提交作业时出现 RestClientException

Question

我在使用以下命令在 flink 1.14 中提交作业时遇到 RestClientException。

flink run -d /<jarname>

这是完整的堆栈跟踪

我无法找到有关此问题的主题。有人可以指导我吗？我在一个新设置的 flink 1.14 版本的 docker 容器中运行它。从下面的行中，它似乎连接到某个地方并且没有连接。可能是某些通信链接无法正常工作。

Response was not valid JSON, but plain-text: Failure: 404 Not Found
