【问题描述】：

我在 AWS EMR 上运行一个 pyspark 集群，并将 Jupyter 用于 pyspark 驱动程序。最近，脚本失败了。 Jupiter 无法启动服务器。我使用conda install jupyter 安装并从sudo initctl start jupyter 开始。集群运行良好。这是服务器的配置值。

# jupyter configs
mkdir -p ~/.jupyter
touch ls ~/.jupyter/jupyter_notebook_config.py
HASHED_PASSWORD=$(python -c "from notebook.auth import passwd; 
print(passwd('$JUPYTER_PASSWORD'))")
echo "c.NotebookApp.password = u'$HASHED_PASSWORD'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.open_browser = False" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.ip = '*'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.notebook_dir = '/mnt/$BUCKET/$FOLDER'" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.ContentsManager.checkpoints_kwargs = {'root_dir': '.checkpoints'}" >> ~/.jupyter/jupyter_notebook_config.py
echo "c.NotebookApp.port = 8080" >> ~/.jupyter/jupyter_notebook_config.py

标签： python pyspark jupyter-notebook jupyter

【解决方案1】：

我发现在更新到 jupyter 5.7 之后。我不得不修改配置参数。改变

echo "c.NotebookApp.ip = '*'" >> ~/.jupyter/jupyter_notebook_config.py

到

echo "c.NotebookApp.ip = '0.0.0.0'" >> ~/.jupyter/jupyter_notebook_config.py

它帮助了我，感谢像这样启动时我遇到了同样的错误：jupyter-notebook --open_browser=False --ip=* 我将其更改为这一行，一切都开始正常工作：jupyter-笔记本 --open_browser=False --ip="0.0.0.0"
@VladimirGorovoy 很高兴它有帮助！
FWIW 这是更改的相关问题：github.com/jupyter/notebook/pull/3714
