[英]AWS EMR PySpark Jupyter notebook not running
I'm working on AWS EMR running PySpark in Jupyter notebook.我正在使用 AWS EMR 在 Jupyter 笔记本中运行 PySpark。 All of a sudden I cannot run the scripts any more.
突然之间,我无法再运行脚本了。 When I click run nothing happens.
当我点击运行时没有任何反应。 Below is a screenshot of when I try to change kernel. No kernels are displayed.
下面是我尝试更改 kernel 时的屏幕截图。没有显示内核。
What's the problem here?这里有什么问题?
I had the same problem, and apparently you also need Livy installed.我有同样的问题,显然你还需要安装 Livy。 If I don't add Livy to the list of apps, I can use the notebook for a few minutes and then it stops working.
如果我不将 Livy 添加到应用程序列表中,我可以使用笔记本几分钟,然后它就会停止工作。 The docs don't mention this at all, but it does mention Livy needs to be there.
文档根本没有提到这一点,但确实提到了 Livy 需要在那里。
