问题描述
我并使用jupyter Notebook的PySpark内核，我已经成功选择了PySpark内核，但仍然出现以下错误
I and using jupyter notebook's PySpark kernel, I have successfully selected PySpark kernel but I keep getting the below error
a)确保Spark有足够的可用资源供Jupyter创建Spark上下文.
a) Make sure Spark has enough available resources for Jupyter to create a Spark context.
b)与Jupyter管理员联系，以确保正确配置了Spark Magics库.
b) Contact your Jupyter administrator to make sure the Spark magics library is configured correctly.
c)重新启动内核.
这也是日志

请注意，我正在尝试在Windows上进行配置.非常感谢
note that I am trying to configure this on windows.thanks alot
推荐答案
如果您尝试通过Juvy将Jupyter Notebook连接到Spark服务器(例如AWS Glue Development Endpoint)，则必须用Spark替换"localhost"服务器IP地址，位于:〜/.sparkmagic/config.json
If you are trying to connect your Jupyter Notebook to a Spark server through Livy (e.g. AWS Glue Development Endpoint), you have to replace "localhost" with the Spark server IP address in: ~/.sparkmagic/config.json
