Question

我正在尝试在AWS EMR集群上启动Flink批处理作业，并得到：

The program finished with the following exception:

我不知道根本原因是什么。在哪里可以找到有关出错原因的更多详细信息？

类似地，我找不到通过Flink / EMR查找成功工作日志的方法。有想法吗？

Answer 1

要查找更多详细信息，您需要JobManager或ResourceManager的更多信息。如果您像许多开发人员一样使用YARN作为群集资源管理框架，则可以访问ApplciationMatser的日志，这些日志是Flink中JobManager的日志。

Answer 2

我遇到了同样的问题，原因是我没有启动flink集群。

./bin/start-cluster.sh

Answer 3

我在本地Mac电脑上以本地模式遇到了此问题。它在maven项目中运行良好，但是在提交给flink本地集群时会在上面抛出异常。

在重新启动Macbook后已解决
